Structure and characteristics of butterfly valve

Butterfly valve is mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical, with a short axial length and a built-in butterfly plate. Features of butterfly valve: 1. The butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid […]

How does a butterfly valve work?

A butterfly valve is a valve that uses a disc-type opening and closing part to reciprocate around 90° to open, close, or regulate the flow of media. Butterfly valves are not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy in […]

How to achieve internal and external anti-corrosion of pneumatic valves

Pneumatic valve using pneumatic actuators, for which Air (or other gas) pressure is the source of power. Air pressure acts on the piston or bellows diaphragm, which produces a linear force on the valve stem. Pneumatic actuator is a kind of Power-operated actuators (using pneumatic, hydraulic or electric power), can remotely adjust valves, or quickly […]
