Gate valve ROCK DN125 CF8M NBR GG25 with pneumatic actuator D.A. ROCK-DA-125-1-C-B

Pneumatic damper – reliable flow control

The ROCK DN125 damper, made of grey cast iron GG25 and equipped with a CF8M disc and NBR seal, is a robust solution for precise flow control in industrial installations. The double-acting pneumatic drive ensures fast and efficient regulation, and the construction materials guarantee long-lasting and trouble-free operation. This is an ideal choice for both installers and end-users looking for a reliable component for automation systems.

Construction and application

The damper is designed to work with media such as compressed air, glycol, oils, natural gas, fuel and water. Thanks to the working pressure of 16 bar, it finds application in a wide range of industrial installations. The construction of grey cast iron (GG25) ensures strength and corrosion resistance, and the disc made of CF8M (stainless steel alloy) guarantees tightness and durability. The NBR (nitrile rubber) seal provides resistance to oils and other industrial media.

Advantages and benefits

• Durable construction: The GG25 grey cast iron body provides solidity and resistance to mechanical damage.
• Wide application: Possibility of use with various media – from compressed air to fuel.
• Efficient control: Double-acting pneumatic drive enables fast and precise flow regulation.
• Tightness: CF8M disc and NBR seal ensure a tight closure of the damper, minimizing the risk of leaks.
• Chemical resistance: NBR seal is resistant to the action of oils and other industrial media.
• Easy integration: Standard size DN125 facilitates installation in existing installations.
• Reliability: High-quality components ensure long-lasting and trouble-free operation of the device.

The ROCK DN125 damper is not only a flow control element, but above all an investment in the reliability and efficiency of your industrial installation. Its solid construction and precise operation translate into minimizing downtime and optimizing production processes.
