The ZZYVP pressure regulating valve with actuator requires no external energy source. It utilizes 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 pressure at the valve's downstream end. Nominal pressure ranges from 1.0 to 1.6 MPa; pressure adjustment segments from 0.5 to 1000 Kpa, with operating temperatures from 0 to 100℃; flange standards comply with GB9113-88, with raised face flanges. Structural length conforms to GB12221-89 standards.
