Pneumatic flow control Angle seat valve

Pneumatic flow control Angle seat valve is made up of Angle seat valve and valve positioner, mainly used to control traffic conditions, is a kind of custom in view of the special conditions of advanced control valve. Pneumatic flow control valve Angle seat valve positioner is a kind of in the controller or control system for 4 ~ 20 ma current signal and converts it into the air pressure, to pneumatic actuators, thus to control the valve opening. Pneumatic flow control Angle seat valve, reaction, easy to convert between single and double effect. With air consumption is small, zero adjustment and range adjustment is very simple, reflect fast, feedback the characteristics of the connection very simple. Smart valve positioner microprocessor with built-in, can be precisely controlled straight trip valve positioning. 4 - using common locator 20 ma current signal, and a variety of functions, the system of high performance and high-end products.
