Pneumatic butterfly valve
The Pneumatic Butterfly Valve is a robust, reliable and versatile valve that can accommodate a wide range of applications – from potable water and wastewater to seawater, HVAC and sanitary & chemical systems. The body of the valve is made from cast iron, ductile iron, aluminum stainless steel, CF8, CF8M, CF3M or double stainless steel (2507/1.4529). The disc is made from stainless steel (CF3M/CF3/CF8M) and has a one-piece disc/stem design which reduces the risk of leaking and pressure drops. It comes with an output torque of 10Nm to 8000Nm and offers control options like Double acting, Single acting normally closed, Single acting normally open etc. It also provides great flange accommodation including EN 1092 PN 6/PN10/PN16 ASME Class 150 , AS 4087 PN 10/ PN 16 , JIS 5K/10K or ISO5211 Top flange. Furthermore its temperature range is -40 °C to + 200 °C depending on material type and pressure. To make using this valve even more convenient it comes equipped with pneumatic accessories such as solenoid valves, limit switch boxes, filters E/P positioners and hand wheels. If you’re looking for reliable performance for your system then look no further than the Pneumatic Butterfly Valve!
