The valve actuator is a product appearing along with the valve and industry automatization. It is used for remote automatic control of valves. The valve actuators include pneumatic type, electric type and hydraulic type.

The pneumatic actuator has such features as simple structure, reliable movement, stable performance, low price, convenient maintenance, fireproof and explosion-proof performance. Furthermore, it can also be used with the electric adjusting meter through electric-pneumatic switching or electric-pneumatic valve positioner. Therefore, they are widely used in such industries as chemical industry, petroleum, metallurgy, power station and etc.
