ZPD series electrical and gas valve locator

ZPD2000 series electric - gas valve positioner and regulator, the regulator output signals, converted to drive the regulator gas signal, can overcome the friction of stuffing box and the valve stem and medium pressure difference to produce unbalanced force of valve core, improve the operation speed regulating valve, to ensure that the regulator according to the controller output signal correct positioning.
