How To Choose A Pneumatic Ball Valve? These Points Are The Key!

Wafer Ball Valve is a ball valve with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast, and the fastest switching speed is 0.05 seconds/time, so it is usually also called a pneumatic quick-cut ball valve. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, air source processing triplexes, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control. The valve switch can be controlled in the control room, and there is no need to go to the site or high altitude and dangerous places for manual control, which saves human resources, time and safety to a great extent.

Speaking of new valves that have been widely used in recent years, pneumatic ball valves have to be mentioned. Pneumatic ball valves are ball valves equipped with pneumatic actuators. In practical applications, they are often used as valves to control the flow direction of the medium in the pipeline. Let's talk about how to choose pneumatic valves.

1. Selection based on working conditions

The temperature of the medium is very important. Some pneumatic ball valves are suitable for handling hot fluids and some are suitable for handling cold fluids. Pneumatic ball valves for different applications are made of different materials, including ceramics, stainless steel metal materials and PVC plastics. When purchasing pneumatic ball valves, you must clarify your actual needs and the application environment of the product.

2. Selection based on working pressure

When the pneumatic valve is closed, it will be subjected to the pressure generated by the accumulation of media in the pipeline. Therefore, when purchasing a pneumatic ball valve, it is necessary to determine the pressure range that the valve needs to withstand when working, and then select the corresponding specifications.

3. Selection based on medium fluid

The actual needs of customers are diverse. Some purchase pneumatic ball valves to handle ordinary flowing water, such as in hydropower plants, while some need to be used to control the flow of chemical media, or even radioactive substances, which requires pneumatic ball valves to be designed with different fluid control systems.

4. Selection based on price

If you are not sure what model to choose when purchasing a ball valve, it is easy to waste money that should not be spent, because the price of pneumatic ball valves is also related to the specifications and models.

There are many companies on the market that specialize in producing and selling valves for industrial applications, but the quality varies. It is easier to suffer losses if you only look for cheap pneumatic ball valves, because the quality can be very poor, so you must combine the above points.
