Butterfly valve ROCK DN125 CF8M EPDM GG25 with pneumatic actuator D.A. ROCK-DA-125-1-A-B

Pneumatic damper – reliable flow control

The ROCK DN125 damper, made of grey cast iron GG25 (EN GJL-250) and equipped with a CF8M disc, is a robust solution for flow regulation in installations. An EPDM seal ensures tightness and resistance to various media. A D.A. type pneumatic actuator enables quick and precise control of the damper, which is particularly important in automated systems.

Design and application

The damper design is designed for reliability and durability. Grey cast iron GG25 is characterized by good mechanical strength and corrosion resistance, which translates into a long service life. The disc made of CF8M (stainless steel alloy) provides resistance to corrosion and abrasion, and the EPDM seal guarantees tightness over a wide range of temperatures and pressures.

The damper is used in water installations, including hot and cold water systems, as well as seawater and alcohol. It can be used in both industrial installations and public or residential buildings. The pneumatic actuator allows for remote control of the damper, which facilitates integration with building or industrial automation systems.

Key features and benefits

• Durable construction: The GG25 grey cast iron body provides solidity and resistance to mechanical damage.
• Chemical resistance: The CF8M disc and EPDM seal guarantee compatibility with various media, including seawater and alcohol.
• Wide temperature range: The damper can operate at temperatures from -10°C to 110°C, making it a universal solution for various applications.
• Precise control: The D.A. pneumatic actuator enables smooth and accurate flow regulation.
• Safety: The working pressure PN16 ensures safe operation of the installation.
• Easy integration: The pneumatic actuator facilitates connection of the damper to automation systems.
