Product Description

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 implementa remote automatic control. Especially suitable for a low differential pressure and mass flow pipelines.
