instructions

EP1000 electricity - gas valve positioner with adjusting penalty to convert the controller output signal to drive the regulator of gas signal, overcome the stuffing box and the friction of the stem, valve positioner overcome medium pressure difference of regulating valve valve core is unbalanced force, speed up the movement of the valve, the valve positioner can realize a relay control signal (section) can change the way valve function to control the various types of non-standard operating pressure pneumatic actuators.
