Collection:Pneumatic 3-Way Stainless Steel Ball Valves

Explore Tameson's wide range of 3-way stainless steel pneumatic ball valves from various global manufacturers. 3-way stainless steel ball valves with pneumatic actuators are used to control the flow of liquids and gasses remotely. 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.

A 3-way stainless steel pneumatic ball valve has three ports. They are available in two design types: L-port and T-port. This refers to the bore design in the ball, which is the media flow path. With a 3-way ball valve T-port or L-port, it is possible to mix, distribute, or divert the media flow. A 3-way T-port ball valve can be used for mixing media from two inlets into a single outlet or for distributing one inlet to two outlets. By changing the position of the handle (90 degrees or 180 degrees), you can change the circuit function. The 3-way L-port ball valve is designed for flow direction control. The L-port valve has a 90-degree bore inside of the ball, hence the name L-port. An example of an application is to have two inputs from separate tanks and one output, and you want to only use one of the inputs but always the one output. L-port ball valves can have 90-degree or 180-degree handles. Ones with a 180-degree turn allow you to disconnect both inputs from the output, allowing for no flow. Therefore, it is important to know your bore design to ensure your desired media flow, as the ports can be in different positions. The pressure inlet for 3-way pneumatic ball valves is typically on the center borehole to avoid leakage unless defined otherwise in the product specifications.

The pneumatic ball valve's stainless steel housing makes them very durable and often a good housing material choice as it generally has a very good overall chemical resistance to almost any medium. Stainless steel is capable of working with aggressive media. These valves are also suitable for water, oil, compressed air, fuels, solvents, and vacuum. The material is highly wear, temperature, and pressure resistant. However, stainless ball valves are unsuitable for hydrochloric acids, chlorides, bromine, and household bleach. Swimming pool water has a low concentration of chlorides, and therefore stainless steel 316 can still be used.
