Gate valve ROCK DN65 CF8M NBR GG25 with pneumatic actuator D.A. ROCK-DA-065-1-C-B

Pneumatic damper – reliable flow control

The ROCK DN65 damper, made of grey cast iron GG25 and equipped with a CF8M disc, is a robust solution for precise flow control in various installations. NBR sealing ensures tightness and compatibility with a wide range of media. The D.A. pneumatic actuator enables quick and efficient opening and closing of the damper, which is particularly important in automated systems.

Design and application

The damper's construction based on grey cast iron (GG25) guarantees strength and corrosion resistance. The disc made of CF8M (stainless steel alloy) ensures durability even in harsh working conditions. NBR (nitrile rubber) was used as a seal due to its resistance to oils, glycol and compressed air. The damper is designed to operate at a working pressure of up to 16 bar.

• Wide range of applications: ideal for compressed air, glycol, oil, natural gas, fuel and water installations.
• Durable construction: grey cast iron GG25 ensures long-term reliability.
• Tightness: NBR sealing minimizes the risk of leaks.
• Precise control: the D.A. pneumatic actuator enables quick and accurate flow regulation.

The ROCK DN65 damper is a component that will work in both new installations and in the modernization of existing industrial or building automation systems. Its solid construction and precise operation translate into the reliability and efficiency of the entire system. The pneumatic actuator facilitates integration with existing control systems, and a wide range of compatible media make it a universal solution for many industries.
