The control valve is the final control element is the most widely used types. The final control element other including metering pump, regulating baffle plate and a louver baffle (a variant of the butterfly), fan blades, current variable inclination adjusting device and the device of motor positioning is different from the valve. Although thevalve has been widely used, other unit regulating system probably are not like thatsmall maintenance workload. In many systems, regulating valve to withstand theworking conditions such as temperature, pressure, corrosion and pollution is moreserious than other components, however, when it control process flow of a fluid, it must run satisfactorily and the least amount of maintenance.

The two part valve by the electric actuator or pneumatic actuator and valvecomponents. Regulating valve is usually split regulating valve and through the two seater valve two is through single seat type, which have large flow capacity, small and unbalance do the characteristics of stable operation, it is usually suitable for high flow,high pressure drop and leak less occasions.
