ZPD-2111 ZPD-2112 ZPD-2211 Valve positioner

Overview of ZPD-2111 ZPD-2112 ZPD-2211 Valve positioner

ZPD-2111 ZPD-2112 ZPD-2211 Valve positioner is the main accessory of the regulating valve, which is usually used together with the pneumatic regulating valve. It receives the output valve positioner signal of the regulator, and then controls the pneumatic regulating valve with its output signal. When the regulating valve acts, the displacement of the valve rod is fed back to the valve positioner through the mechanical device, and the valve position status is transmitted to the upper system through the electrical signal. Electric valve positioner is the main accessory of control valve.
