Description
High temperature pneumatic damper butterfly valve
The High Temperature Pneumatic Damper Butterfly Valve exists as a durable product which delivers excellent operational results. The advanced damper valve includes a metal face seal design with central line structure and strong metal seat which reduces leakage. The valve operates at temperatures up to 980°C while supporting PN 6 to PN 16 pressure ratings and following EN 1092 and ASME Class 150 and AS 4087 and JIS 5K/10K standards. The air damper butterfly valve performs both on/off and throttling operations through its optional pneumatic actuator which provides torque from 10Nm to 8000Nm. The valve operates well in steel and petrochemical and power station environments.

FAQs
What is damper butterfly valve?
The damper butterfly valve functions as a rotary control valve which enables the management of liquid and gas flow. The damper butterfly valve serves multiple industries including chemical operations and power plants and oil and gas facilities and iron and steel manufacturing and food processing facilities. The damper butterfly valve consists of two main parts which include a disc-shaped disc attached to an axle that runs through its center and an actuator system that rotates the disc between different positions.
What types of media can the Damper Butterfly Valve be used with?
The Damper Butterfly Valve operates with different types of media because it works with gases and hydraulic oil and water and steam. The valve operates dependably at high temperatures because its strong design allows it to handle fluids up to 980°C.
In which industries is the Damper Butterfly Valve commonly used?
The valve finds widespread application in steel production and petrochemical processing and power generation and building materials manufacturing. The valve operates effectively in demanding industrial settings because it can handle both high temperatures and high pressures.
