High Temperature Butterfly Valve
Introduction:
As a component used to realize the on-off and flow control of the pipeline system, the high-temperature butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower.
Application:
High-temperature butterfly valves are widely used in high-temperature gas pipelines in metallurgy, building materials, chemicals, power stations, glass and other industries. As a device for regulating or cutting off high-temperature gas medium flow, high-temperature butterfly valves can be used with various actuators to form equipment with different performances.
Features:
1. The sealing surface of the valve seat and the sealing ring of the butterfly plate are all metal parts, which will not deform under thermal stress and ensure fire safety.
2. The butterfly plate sealing ring of the high-temperature butterfly valve can be smoothly detached from the sealing surface of the valve seat and rotate without friction, which is suitable for frequent opening and closing applications.
3. Under the action of the driving device, the high-temperature butterfly valve achieves elastic sealing through torque, and the butterfly plate can closely contact the valve seat, effectively ensuring the sealing specific pressure, so that it has two-way sealing and zero leakage performance.
4. The high temperature butterfly valve also has the functions of regulating flow, cutting off medium and bidirectional sealing. In the event of an accidental power outage or abnormality in the pipeline, the medium can be reversely sealed.
