ZZYP-Ⅱ REGULATOR is a pilot self-operated pressure regulating valve which has all the advantages of which ZZY REGULATORS self-operated pressure regulating valve possesses (Please refer to the details of our ZZY REGULATOR),especially,it has the following advantages: 1.it’s convenient and quick for pressure setting; 2.Regulating accuracy is high,so it’s suitable for high precision regulating conditions;3.Regulating range is wide;4.Reaction is sensitive,low pressure and small pressure difference can be feedback.

This regulator is suitable for the following working conditions:1.Used as a tiny pressure regulating valve to take the place of ZZV REGULATOR( Please refer to the details of our ZZV REGULATOR);2.Used as nitrogen closure device.The refined oil in the nitrogen closure tank is usually covered with nitrogen,it’s pressure is usually very low as about 100mmH2O,this regulator can regulate the pressure at low and high precision level to protect the tank in safety condition.This regulator is designed and manufactured according to the standard of AMSE/API/BS/DIN/GB
