Product Details

For ZZY/ZZC/ZZV 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.
