The ZZYVP pressure regulating valve with actuator operates without external power, utilizing the energy of the medium being adjusted as the power source. The actuator introduced into the pressure valve controls the position of the valve core, altering the flow rate of the medium passing through the valve, thus maintaining a constant back-end pressure. The nominal pressure ranges from 1.0 to 1.6 MPa; pressure segment adjustment is from 0.5 to 1000 Kpa, with operating temperature from 0 to 100℃; flange standards comply with GB9113-88, with raised face flanges. The structural length adheres to GB12221-89 standards.
