Pneumatic valves are valves that are operated with a pneumatic actuator. An actuator is no more than a device that turns 90, 180 or 270 degrees under air pressure to close or open the valve. We provide our pneumatic valves in many types and sizes. 2-way valves, 3-way valves, valves with a flange connection, weld connection of with screw-thread. With our ball valves, you can even choose between having them in 2 or 3 parts. Specifications: Pressure: up to about 500 bars Measurements: up to about DN1400 Materials: stainless steel, messing, ASTM, carbon steel, PVC and many more The pneumatic valves of OpenSupply can be provided in almost any material. For instance, stainless steel, messing, ASTM or carbon steel. Our pneumatic actuators are usually made from an aluminum alloy, ASTM6005. This is a hard anodized alloy that makes the casing wear-proof and offers good protection against corrosion. There are 2 categories of pneumatic valves: direct action (air open/air closed) or spring return (air open/spring tension closed). Our pneumatic valves can be equipped with limit switches, hand grips, positioners, sprocket casings and Namur adapters. Many of our valves can be provided with quality marks/certificates, like Atex II2, AP1607 or NACE MR-0175.
