High temperature butterfly valve is widely used in petroleum, chemical industry, metallurgy, water and electricity and many other fields of high temperature piping, Optional flange connection or wafer connection, with corrugated heat shield, so it is more resistant to high temperature than normal butterfly valve
Multilayer soft fold type sealing ring is fixed on the valve plate. the butterfly valve and the traditional butterfly valve compared with high temperature resistant, convenient operation, opening and closing without friction, close to the actuator torque increases to compensate for sealing, improve the butterfly valve sealing performance and prolong the service life of the advantages.
Frequently Asked Questions
What temperature information is needed to select this high-temperature valve?
Provide normal and design temperatures, pressure conditions and any cycling or startup requirements. Request confirmation of the allowable conditions for the complete body, trim and sealing assembly rather than selecting from the product name.
Should I order a flanged or wafer connection?
Use the piping connection and installation requirements for your project. Send the mating dimensions and available space and request the selected valve drawing instead of assuming the two body patterns are dimensionally interchangeable.
What operating arrangement should I confirm near a hot pipeline?
Show the intended operator position, insulation and nearby equipment and ask for the selected assembly’s operating and maintenance requirements. Do not assume the operator or exposed surfaces are safe to touch from a temperature-service description.
