High temperature pneumatic damper butterfly valve
We are proud to offer our customers the High Temperature Pneumatic Damper Butterfly Valve. Constructed from some of the highest quality materials, this low load butterfly valve features a metal face seal design with a central line structure and metal seat that surrounds the disc. This clever design reduces seat leakage while still delivering on mature manufacturing technology for convenient maintenance and product reliability. It’s suitable for a variety of fluids at temperatures up to 980°C and pressure services between PN 6 – PN 16 with flange accommodation across EN 1092, ASME Class 150, AS 4087 and JIS 5K/10K standards. With optional pneumatic actuators available in torques ranging from 10Nm to 8000 Nm, this butterfly valve is suitable for both on/off and throttling applications and compatible with other media such as hydraulic oil or water. This butterfly valve is suitable for steel, building materials, petrochemical industries, power station and more. Get your High Temperature Pneumatic Damper Butterfly Valve today!
low load butterfly valve adopts the metal face seal design of central line structure. The metal seat surrounds the disc. This structure can reduce the seat leakage. Featured by simple structure, light weight, mature manufacturing technology and convenient maintenance, the butterfly valve is used for flow and pressure control in low pressure service conditions and is suitable for fluids of very high temperature. It is widely used in steel, building materials, petrochemical industry, power station and other industries.
