Chinese MSP-25 series intelligent valve positioner is a control device that controls the valve opening by receiving the 4-20mA command signal sent by the controller or control system and converting it into a pneumatic signal to drive the pneumatic actuator to control the valve opening. Valve position control of quarter-turn valves.
◇Adopt pressure valve electric/pneumatic conversion structure.
◇It can be used for pneumatic valves of different specifications.
◇Easy installation and debugging.
◇With LCD backlight display and button operation.
◇Three-stage protection function can be realized.
