Manual Cast Steel Butterfly Valve
Introduction:
Butterfly valve is a valve that uses a circular butterfly plate as a opening and closing part and rotates with the stem to open, close and adjust the fluid channel. Butterfly valve is not only simple structure, small volume, light weight, material consumption, small installation size, and small driving torque, simple operation, rapid, and also has good flow regulation function and close sealing characteristics, in large and medium diameter, low pressure in the field of use, butterfly valve is the dominant form of the valve. With the application of anticorrosive synthetic rubber and PTFE, the performance of butterfly valve can be improved and meet different working conditions.
Application:
It is widely used in water supply and drainage, sewage, construction, air conditioning, petroleum, chemical industry, food, medical, textile, paper making, water and electricity, ships, metallurgy, energy system and other fluid pipelines as regulating and intercepting devices.
