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 conductor, and can be adjusted at will in the operation, so that it is convenient, quick and labor-saving;The control precision is about twice as high as the general pressure regulating valve.
