[Valve features]
      Pilot operated pressure control valve (single seat valve, referred to as n) of the valve without any external energy, the use of adjusted medium (gas) energy as the power source, the detection of actuator into the command device, to control the position of the valve core valve, changing the medium flow through the valve, the valve the pressure is maintained at a constant value. The characteristic of the valve is that the pressure setting value can be realized on the command device, and can be adjusted freely during operation. The utility model is convenient, quick and labor-saving, and the control accuracy is about twice as high as that of the general regulating valve.

[Adaptive condition]
       Widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, filling equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology the.
