UI8000 series self-operated pressure control valve makes use of the media self-energy to automatically modulate the valve. The unique characteristic of the valve is that it can work in the place without electricity and gas, which is an energy saving and environmental product. With acute action, the pressure set value can be modulated during operation according to on-site pressure requirement. Ordinary product can adopt quick open characteristic, linear and EQ also can be adopted. It is widely used to reduce pressure, stabilize pressure ( to control outlet pressure) or release pressure, stabilize pressure ( to control inlet pressure)of gas, fluid, steam media in petroleum, chemical, power, metallurgy, food, light textile, resident building ect. Various industrial equipment.
) For UI8000 series self-operating regulating valves, there is no need for any external power source, used fluid adjusted by own energy to regulate automatically, saving power source, pressure set value can be adjusted free during working, quick-opening flow, flexible operation, good sealing property, stable medium pressure, high regulating precision and low leakage. ZZY series self-operating pressure regulating valve(also called pressure regulating valve for short).
The valve needn't air supply, which is self-operating which can work without airsupply and electrical signal. It saves too much energy, and the pressure can be regulating anytime. The valve works on quick open flow characteristic, action quickly after service condition changed, and sealed well. So the valves are used for so many field, such as petrotech, chemical industry, power station, metal industrial, food, textile, machine manufacture, and construction etc.
2) This series of products includes many type such as UI8100 standard(self-operated regulating valve), (self-operated regulating valve with operated director)(self-operated pressure difference regulating valve) ( self-operated micro-pressure nitrogen-sealing regulating valve). The PN grade of this series of products are 150LB, 300LB and 600LB, 900LB, the body DN about 1/2-12 inches, the leakage standard is IV grade or V grade, the flow property is quick opening and sorts of specification are optional.
