ROCK butterfly valve DN50 CF8M NBR GG25 with pneumatic actuator D.A. ROCK-DA-050-1-C-B

Pneumatic damper for various applications

The ROCK DN50 damper, made of gray cast iron GG25 and equipped with a CF8M disc and NBR seal, is a reliable solution for precise flow control in industrial installations. The double-acting pneumatic drive ensures fast and efficient operation, and the construction materials guarantee corrosion resistance and long-term operation.

Construction and application

The damper construction is based on a body made of gray cast iron (EN GJL-250), which ensures strength and stability. The disc made of CF8M (stainless steel alloy) is characterized by high resistance to abrasion and corrosion. The NBR (nitrile rubber) seal ensures tightness over a wide range of temperatures and pressures. The damper is designed to work with various media, such as compressed air, glycol, oils, natural gas, fuel and water. This makes it applicable in many branches of industry – from industrial automation to HVAC installations.
