Types of Trunnion Ball Valve
Top Entry Trunnion Mounted Ball Valve
This type of ball valve has a removable bonnet cover on the top of the valve. The internal parts of the valve can be easily accessed by removing the bonnet. These valves are easy to assemble and disassemble. You can repair or maintain different parts of the trunnion valve without removing it from the pipeline.
Side Entry Trunnion Mounted Ball Valve
Side entry ball valves are also known as split body trunnion mounted ball valves. In these valves, the body is divided into two or three pieces that are bolted together like flanges. One piece of the body is always larger than the rest. The larger piece holds the ball as well as the stuffing that goes around the ball. These valves are easier to inspect and repair as the smaller piece can be removed to access the valve.
Full Port Trunnion Mounted Ball Valves
In full bore valves, the size of the diameter of the bore matches that of the connected pipeline. When the valve is open, the medium can flow freely without restriction through the bore. This type of ball valve is used in chemical, petrochemical, and refining industries. They are also used in applications where pigging is required.
Half Port Trunnion Mounted Ball Valve
A half port trunnion valve has a bore size that is a few nominal sizes less than the diameter of the connected pipeline. The flow path of the medium is restricted which results in higher energy losses. Half port valves are mostly used in the oil and gas industry.

Components of Trunnion Ball Valve
Body
The ball valve's body is the casing that supports the inside of the valve and keeps it in place. Based on the function it will receive, the substance for this design may be constructed of various products. Carbon steel, stainless steel, duplex, low-temperature carbon steel, Inconel, and super duplex are a few of the materials that are frequently utilized.
Ball
It rotates through a disc with a sphere-like form to halt or start flow in a steady rotation. On one end, it is attached to the Trunnion, and on the other, to the stem. While it takes turns, the ball is secured in place. The seats of the Trunnion ball valve frequently get into touch with this ball, lowering the torque.
Seat
The Trunnion ball valve's seat is a design element that encircles the ball. The seats hold the ball firmly in place when the actuator is switched on, preventing access. There are two varieties: soft and metal, which causes it to move in the ball's general direction.
Trunnion
The trunnion ball valve has an additional shaft that holds the ball in place from below, which is called Trunnion. Its purpose is to maintain the ball's tight attachment. In some Trunnion mounted ball valves, the Trunnion is an attachment of the spherical ball, and the rest of the time, it is connected to the spherical ball disc through welded joints.
Stem
The ball and the actuator are connected by the trunnion ball valve's stem. It is attached to the ball by an extra shaft, which aids in keeping the ball firmly in position. Additionally, it controls how the ball moves. Trunnion-mounted ball valves retain stronger anti-blowout stems, which allows them to withstand high pressures and temperatures without suffering any harm.
Disk
A perforated, solid ball is the shape of the disc in a Trunnion ball valve. The ball is attached to the stem on one side, and on the other, to the Trunnion. The ball or disc in a Trunnion ball valve is stabilized while it revolves. Because the seats are always in touch with the ball, torque is decreased.
Actuator
A trunnion ball valve's actuator is utilized to open or shut down the valve. Based on the application and medium, like air-operated ball valves, numerous types of actuators are utilized in ball valves. On a valve, typical actuators include bare stems, hand levers, pneumatic actuators, gears, and hydraulic actuators. Additionally, you can utilize a motor-operated actuator, a hydraulic-operated actuator, an electric actuator, a gas actuator, gas-over-oil actuator, and more.
Injection
In the seat and stem region, injection fittings are created. Grease can be inserted using a sealant injection fitting when sealing is weakened, and leakage starts. A partial seal is created by the injected sealant to halt additional leaking. The sealant injection fittings are only to be utilized in emergencies.

A Trunnion Ball Valve, as its name perfectly advises, in any valve that utilizes a ball to manage the flow of substances from one opening to the next. The middle of the ball contains a port, sometimes known as a bore. The ball valve is the open place when this central port is aligned up in the same direction as the linked pipeline as such a positioning permits the gas or fluid to flow through. The ball valve turns to the closed place when the port becomes perpendicular, stopping the flow path and stopping any substances to continue moving through.
While most standard ball valves are designed with unique stop measures that allow only a ninety degree rotation, there are few that provide a complete 360 degrees. The 90 degree rotation is exactly all that is needed for the closing and opening of the ball valves, but there are some applications where it is more desirable to have the complete movement of the core. This makes them particularly perfect for industries carrying potent gasses or chemical that wants safe and speeding shutoff, such as with natural gas.
