YD8000 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.
