Collection:2-Way Pneumatic Ball Valves

Explore Tameson's wide range of 2-way pneumatic brass ball valves from various global manufacturers. 2-way pneumatic ball valves are used to control the flow of a media (liquid or gas) by means of a rotating ball with a bore. Pneumatic actuators control ball valves by converting compressed air energy to mechanical motion. The rotating ball is controlled and turned by a pneumatic actuator. For larger valves, pneumatically actuated ball valves are more reliable and cost-effective compared to electric ball valves. 2-way pneumatic brass ball valves are commonly used for remote flow control, like a water pipe or air hose.

A 2-way pneumatic ball valve has two ports (an inlet and an outlet) and a ball with a bore in it. The pneumatic actuator can turn the ball 90 degrees from open to closed (or closed to open), which is why they are often called quarter-turn ball valves or shut-off valves. If the pneumatic ball valve is open, the media will flow from the inlet, through the ball's bore, and out of the outlet. If the valve is closed, the media flow is shut off. They are often called an on/off ball valve with a pneumatic actuator. 2-way pneumatic brass ball valves are one of the most common valves due to their simple operation, reliability, long service life, and wide range of applications.

Brass is an alloy of copper and zinc and has great mechanical properties. Brass ball valves are known for their durability and no leakage over their lifespan, even if they have not been used for a long period of time. These ball valves can be used with drinking water, gas, mineral oils, compressed air, and many other non-aggressive media. However, they are not suitable for use with salt water or distilled water due to the risk of dezincification. Dezincification reduces the mechanical strength of the brass by causing the zinc to be removed from the alloy resulting in a porous structure. However, brass ball valves are more resistant to contaminated media as compared to other types of housing material and provides reliable sealing even in case of dirty media. Brass ball valves can withstand high pressure, high temperature, and high flow rates. Pneumatic 2-way brass valves are also economical due to their simple and robust design, low cost, and low maintenance needs. Due to these advantages, pneumatic brass ball valves are used in a wide range of residential and industrial applications like controlling domestic hot and cold water systems, steam applications, irrigation systems, natural gas systems, marine industries, fire protection applications, and chemical industries.
