What is Orbit Ball Valve

Orbit valve is one common type of ball valve. Seal rubbing is prevented by the tilt and turn mechanism used by orbit valves. In ball valves, gate valves, and plug valves, seal rubbing is the primary reason for failure. These valves have sturdy seals that are primarily built of metal to improve their capacity to function in demanding and hostile environments.Flow lines, dryer switching, emergency shutdown, bypass and block, product segregation, suction isolation, and discharge are just a few applications where orbit valves are appropriate. Orbit valves are employed by a number of industries, including the petrochemical, gas, and oil sectors.

Benefits of Orbit Ball Valve

Excellent Shut-off Capability

Orbit Ball Valve provide a tight seal, ensuring complete shut-off and preventing leakage. The spherical closure design of ball valves allows for a reliable and secure shut-off, even in high-pressure systems.

Quick and Easy Operation

They have a simple design and are easy to open and close, requiring a quarter turn of the handle or lever. This quick operation saves time and allows for efficient control of fluid flow.

Minimal Pressure Drop

Orbit Ball Valve have low friction loss, resulting in minimal pressure drop across the valve. This characteristic is essential in applications where maintaining system pressure is crucial, as it helps minimize energy consumption and ensures efficient flow control.

Wide Range of Applications

Orbit Ball Valve are suitable for various industries, including oil and gas, chemical, water treatment, and HVAC systems. Their versatility stems from their ability to handle a wide range of temperatures, pressures, and fluid types.

Good Flow Control

Orbit Ball Valve offer precise control over the flow rate, allowing for smooth operation and modulation. The quarter-turn operation and the ability to achieve full or partial flow make them effective in controlling the flow of fluids in both simple and complex systems.

Types of Orbit Ball Valve

Manual orbit ball valves

A manual actuator is used to regulate fluid flow in manual orbit valve models. These valves utilize a handwheel mechanism to improve flow control instead of requiring external power. A number of gears in the valve’s mechanism increase production torque in relation to the input torque that the valve operator applies.The advantage of manual orbit valves is that they are affordable, dependable, and independent of outer power sources such as pneumatics and electricity. Since these valves are self-contained and utilize the exact handwheel to unlock and shut down, it is simple for the operator to identify the root of any technical issues or mistakes.

Hydraulic orbit ball valves

Fluid under pressure is utilized by hydraulic orbit valves to regulate the flow of the liquid. These valves employ oil or water as the hydraulic liquid. The piston rolls as a result of the fluid’s pressure, regulating the fluid flow. Hydraulic orbit valves come in semi-automatic and automated varieties.In comparison to pneumatic orbit valves of the exact size, the hydraulic orbit valves tend to be more robust. Due to the incompressibility of the liquid, these valves can accomplish fine fluid control with low energy loss. However, to improve liquid flow, hydraulic orbit valves require an extra hydraulic pipe. Additionally, these valves might leak hydraulic liquid, which increases the chance of a high fire risk.

Pneumatic orbit ball valves

Pneumatic orbit valves are those that are operated by compressed air. These valves operate by applying air pressure to the piston or diaphragm that is fastened to the valve stem. Pneumatic orbit valves, in contrast to manual orbit valves, can be fully or partially automated.Because of the subtle design and dependability, the pneumatic orbit valves are the most popular form of orbit valve. The benefits of pneumatic orbit valves are little to no fire hazards, simple and dependable design, manageable operation, and inexpensive prices. But, these valves might not work well at slow speeds.

Electric orbit ball valves

Valves that rely on electricity to function are known as electric orbit valves. Electric motors are utilized in these valves to transform electrical energy into mechanical energy sufficient for unlocking and shutting down the valve. As they can be opened and closed manually, automatically, or semi-automatically, the electric orbit valves are highly flexible.The motor in electric orbit valves can move both ways, and it aids in gearing up the valve stem. Electric orbit valves have the benefit of not requiring liquid or pressurized air and being able to provide extremely high torque for heavy-duty uses. However, in comparison to manual and pneumatic orbit valves, these valves are highly costly. In addition to that, the electric orbit valves are also prone to power outages and fire hazards.

The Material Behind The Orbit Ball Valve

Stainless Steel
Known for its corrosion resistance, stainless steel is often used in valves for applications where the fluid being handled is corrosive. Different grades of stainless-steel offer varying levels of corrosion resistance.

Carbon Steel
Carbon steel is a robust material commonly used in valves for industrial applications. It is strong and durable, but it may be susceptible to corrosion, so protective coatings or treatments may be applied.

Alloy Steel
Alloy steel is a combination of various elements, including chromium, nickel, and molybdenum. This alloying enhances properties such as strength and corrosion resistance, making it suitable for demanding applications.

Brass
Brass valves are known for their excellent conductivity and corrosion resistance. They are commonly used in applications where the fluid being handled is non-corrosive.

Nickel-Alloy
Certain valves designed for extreme conditions, such as high temperatures or corrosive environments, may be constructed from nickel alloys. These alloys offer excellent resistance to corrosion and oxidation.

Components of Orbit Ball Valve

Valve body

The body of the Orbit Ball Valve is typically made of forged or cast steel, offering high strength and corrosion resistance, and is capable of withstanding high-pressure and high-temperature environments.

Ball

The ball moves within the valve body through a specially designed track and is usually made of stainless steel or nickel-based alloys, providing excellent wear and corrosion resistance.

Seat

The seat is the part that comes into contact with the ball, typically made of metal to ensure sealing performance under high pressure and high temperature conditions.

Stem

The stem connects the ball to the actuator, responsible for transmitting operational torque to move the ball within the valve body.

Sealing System

This includes the seat seal and stem seal, ensuring no leakage of the medium. Seals are typically made of metal or high-performance polymer materials.

Actuator

This includes manual operation mechanisms or automated actuators used to control the opening and closing of the valve.

Features Of Orbit Ball Valve

No scraping Between sealing surfaces

In conventional ball valves, gate valves, and plug valves, seat wear is mostly brought on by seal abrasion, which is eradicated by the tilt-and-turn movement.

Individual Seat Design

The orbit valve eliminates the issues associated with trapped pressure between labels by using an individual, fixed seat that seals in double directions.

Maximal Flow

High CV numbers are produced by full port or reduced port apertures. Both erosion issues and system pumping efficiency are improved.

Top-entry Structure

The top-entry structure facilitates maintenance by allowing in-line examination and repair after system depressurization.

Extended Lifespan

The long-lasting orbit valves can replace other problematic gate valves, plug valves, and globe valves. The orbit valve architecture delivers performance benefits that lower maintenance costs and plant outages.

Injectable Packing

In order to completely regulate fugitive emissions during in-service care and maintenance, stem stuffing substance is pumped through the packing fitting.

How to Choose Orbit Ball Valve

Temperature Range
Orbital valves can function in a variety of pressure ranges. However, the producers of orbit valves provide the valves with a particular operational temperature range. Knowing the media’s lowest and maximum temperatures is crucial before buying the orbit valves. The valve could get harmed by elevated temperatures. On the other hand, it is possible for the valve to freeze at extremely low temperatures.

Pressure Rating
Manufacturers of orbit valves design their valves with varying strengths to accommodate various pressure levels. As a result, before choosing an orbit valve, consider how much pressure it will be subjected to. Depending on the amount of pressure the media will exert, this can be specified. The orbit valve will be harmed or the valve operator will be hurt if the fluid pressure strength is greater than the strength of the valve.

Power source for the orbit valve
An orbit valve’s opening and shutting require some power in order to provide a turning effect for shutting down or opening the valve. The actuator to be utilized is determined by the power source. As a result, choose the orbit valve depending on the actuator type that is available: manual (hand-operated), pneumatic, hydraulic, or electrical.

Size of the valve
It is crucial to know the size of the valve so you can get an orbit valve that will match the other plumping components without difficulty. In addition to that, this will prevent the need to modify the piping system or guarantee that the orbit valve does not collide with other piping system parts.

Environmental conditions
In this situation, the valve may be disclosed to elements that could impair its functionality, like extreme heat or cold and corrosive media. If the valve is operating with volatile materials like petroleum, a hot environment could harm it or even set it on fire. Freezing can happen at extremely less temperatures. Corrosive substances can weaken the valve body by damaging exterior valve components including screws, nuts, and bolts.

Weight and assistance
The weight and support of the orbit valve must be taken into account. A few valves are quite hefty, and this may put a lot of strain on other pumping parts, eventually causing them to fail.

FAQ

Q: Should the ball valve be the same size as pipe?

A: Measure the Inside Diameter (ID) of the pipe, this is the distance across the pipe's inner surface from one side to the other. Once you have identified the ID, choose a ball valve that is closest to that size. Ball valves are typically labeled in inches for the pipe they will fit, not the ball valves physical size.

Q: What is the difference between ball valve and orbit ball valve?

Q: What size valve should I use?

A: As a general rule, the maximum capacity of a control valve should be 15-50% above the maximum process flow, and the minimum required Cv must be within the available rangeability of the valve for proper control.The best way to install a ball valve is to install the valve with the valve stem facing upwards. Connecting the valve in any other way may cause dirt buildup within the valve stem and is not recommended.

Q: Is there a correct way to install a ball valve?

A: Ball valves may be installed in vertical or horizontal pipe runs, they are bi-directional therefore flow direction is not critical, however the best practice is to set up the valve handle to point in the direction of flow whenever possible.

Q: Does a ball valve reduce water flow?

A: As the valve handle turns, the ball also turns, reducing the size of the opening. This decreases the flow rate and can lead to a perceived decrease in water pressure. It affects outlets like faucets or showerheads. However, a ball valve doesn't actually reduce the system's inherent pressure; it only restricts the flow.

Q: How do I know which valve to use?

A: First, you have to know what function you want the valve to perform. Whether it is for the prevention of backflow, flow control, separation of two different fluids or for other functions. Another consideration is size. You should make sure the valve you are selecting is a proper fit for the pipe.

Q: What is the difference between a ball valve and a slip ball valve?

A: Slip ball valves are ideal for low torque and high-pressure applications. Ball valves are cost-effective for low pressure systems. When selecting a valve, consider fluid type, temperature, pressure, size, and location. Weighing pros and cons ensure performance, efficiency, safety, and cost-effectiveness.

Q: Are all ball valves the same?

A: There are five general body styles of ball valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled. The valve operation is the same in each case.

Q: Why does my ball valve keep dripping?

A: Over time, the stem packing can become worn or damaged, causing it to lose its sealing ability and allowing fluid to leak out. Bent or misaligned stem: A bent or misaligned stem may not be able to turn properly, causing it to rub against the valve body and wear out the stem packing.

Q: What are the longest lasting ball valves?

A: Stainless steel ball valves offer a long-lasting option, even when used in highly corrosive environments; 316 stainless steel is a particularly corrosion-resistant alternative that includes more nickel than standard stainless steel, as well as the addition of molybdenum — a silvery metal with a very high melting point.

Q: Do ball valves need to be exercised?

A: Many people choose metal seated ball valves for these applications because they are less prone to corrosion and need less frequent exercising compared to other valves. However, every valve should go through periodic cycle testing. Most people conduct valve exercise programs annually.

Q: Why choose ball valve?

A: Low Flow Resistance: Ball valves exhibit minimal flow resistance, ensuring efficient fluid movement within pipelines. Corrosion Resistance: Suitable for use in corrosive media and low boiling liquids, ball valves demonstrate reliability even in challenging environments.

Q: What is the difference between a ball valve and an orbit valve?

A: Unlike traditional ball valves where the ball simply rotates to open or close, ORBIT valves employ a unique tilt-and-turn mechanism to decrease seal rubbing. It is specifically designed to regulate the flow of fluids in industrial processes.Brass is more expensive than PVC and can resist corrosion better than plastic valves. It can withstand more heat than plastic, making brass valves an optimal choice for home plumbing systems.

Q: What is the preferred pressure end of an orbit valve?

A: Orient the valve so that the preferred pressure end will be toward the higher pressure when the valve is closed. because it reduces wear and because the valve may be rated at a different working pressure when installed in the opposite direction.

Q: Is a ball valve better than a pressure regulator?
