    Summary of Commander Operational Self-powered Single Seat Pressure Regulating Valve

    Commander-operated self-powered single-seat pressure regulating valve (referred to as nitrogen supply valve), which does not need additional energy, uses the energy of the regulated medium (gas) as the power source, and introduces the detection and execution mechanism of the commander to control the position of the valve core, change the medium flow through the valve, so as to keep the pressure behind the valve constant. Value. The characteristics of the valve are as follows: the pressure setting value can be realized on the commander, and can be adjusted at will in operation, so it is convenient, fast and labor-saving; the control accuracy is about twice as high as that of the general pressure regulating valve.
