Butt Weld Ball Valve

Butt Weld floating ball valves are manufactured in accordance with API 6D. The valve is configured in a forged bolted two-piece split-body design with a small diameter, suitable for medium/low pressure working conditions. Characterized by simple design, the valve seats are directly inserted into the body.
The upstream flow pressure pushes the free-floating ball against the downstream seat-the resulting compression provides a perfect leak-free sealing solution.
The stem is connected at the top of the ball and allowing the valve to open and close with a quarter-turn movement.
Material selection is fully customizable to meet the customer's project specifications and several unique features are available offering an enhanced technical solution suitable for aggressive offshore environment and corrosive and abrasive fluids.

How to choose a suitable floating ball valve Based on performance parameters?

When choosing a suitable floating ball valve, it is very important to consider performance parameters. Here are some suggestions, presented in a point-by-point and summary form, to help you choose a suitable floating ball valve:

1. Determine the characteristics of the medium

· Medium type: Understand whether the medium flowing in the pipeline is water, oil, gas or other liquids to ensure that the selected floating ball valve is compatible with the medium.

· Medium temperature and pressure: According to the temperature and pressure range of the medium, select a floating ball valve with the corresponding nominal pressure and applicable temperature.

2. Consider the pipeline size

· Nominal diameter: According to the size of the pipeline, select a floating ball valve with an appropriate nominal diameter to ensure that the connection between the valve and the pipeline is tight and leak-free.

3. Evaluate valve performance

· Sealing performance: Select a floating ball valve with excellent sealing performance to ensure that the valve can effectively prevent medium leakage when it is closed.

· Flow capacity: According to the flow requirements of the pipeline, select a floating ball valve with sufficient flow capacity to ensure that the medium can pass smoothly.

· Operational flexibility: Choose a floating ball valve that is easy to operate and flexible so that the valve can be opened or closed quickly and accurately when needed.

4. Consider the material

· Valve body material: According to the medium and working environment, choose a suitable valve body material, such as carbon steel, stainless steel, etc., to ensure the corrosion resistance and durability of the valve.

· Sealing material: Choose a sealing material with excellent sealing performance, such as soft alloy sealing ring, etc., to improve the sealing performance and service life of the valve.

5. Evaluate other factors

· Explosion-proof performance: If the medium has flammable and explosive characteristics, a floating ball valve with explosion-proof performance should be selected to ensure that the valve will not break or leak under abnormal circumstances.

· Brand and quality: Choose a well-known brand and a floating ball valve manufacturer with a good reputation to ensure the quality and reliability of the valve.

6. Comprehensive comparison and selection

· Compare floating ball valves of different models and brands: According to the above factors, compare the performance parameters, prices, after-sales services, etc. of floating ball valves of different models and brands, and choose the product with the highest cost performance.

· Consider actual needs and budget: When choosing a floating ball valve, you should fully consider the actual needs and budget, choose products that meet the actual needs, and control the cost within a reasonable range.

In short, when choosing a suitable floating ball valve, you should comprehensively consider factors such as medium characteristics, pipeline size, valve performance, material, explosion-proof performance, brand and quality, and make a comprehensive comparison and selection.
