ZZDVP controller operated self operated single seat pressure regulating valve (referred to as nitrogen supply valve), which does not require external energy and uses the energy of the regulated medium (gas) itself as a power source. The detection and execution mechanism of the controller is introduced to control the position of the valve core of the pressure regulating valve, change the flow rate of the medium passing through the valve, and maintain a constant pressure behind the valve. The characteristics of this valve: the pressure setting value can be achieved on the controller and can be adjusted freely during operation, making it convenient, fast, and labor-saving; The control accuracy is about twice as high as that of a typical pressure regulating valve.

Overview of Self operated Pressure Regulating Valve with Commander:

The self operated pressure regulating valve with a commander consists of a control valve (main valve), an actuator, and a commander. It relies on the pressure of the regulated medium itself as a power source to achieve automatic regulation and stable pressure. It is suitable for pressure reduction and stabilization situations with large adjustable ratios and large pressure differentials.

The self operated pressure regulating valve with a commander is mainly used for gas pressure reduction and stabilization, with a large adjustable ratio and a wide adjustable range. It is particularly suitable for situations where the pressure in front of the valve is high (up to 1.0MPa) and the set pressure is low (up to 14mm water column/0.14KPa). It can be used for pressure regulation of non corrosive gases/liquids and other media that require secondary or tertiary pressure reduction according to conventional requirements.
