High Temperature Ventilation Butterfly Valve
High temperature ventilation butterfly valve operated by pneumatic or electric actuator, with a special designed metal seat keep valve plate to a flat seal without lining structure, thus significantly reduce operating torque. Additional install a radiator between the valve and actuator, avoid the influence of the high temperature possible heat transfer to the actuator. Widely use for cold and hot flue gas pipeline, that implement a remote automatic control. Especially suitable for a low differential pressure and mass flow pipelines.
