Operational command device self-reliance type single-seat pressure regulator (hereinafter referred to as for nitrogen valve), the valve does not need additional energy, energy (gas) modulated medium itself is used as the source of power, introducing command device detection enforcement agencies, to control the pressure regulating valve valve core position, change the medium flow through the valve, keep the valve after pressure at a constant value. The characteristics of the valve: the pressure setting value can be realized on the controller, and can be adjusted in the operation, so it is convenient, quick and easy to save. The control precision is about twice as high as the normal pressure control valve.
