Valve Type: Self-operated pressure control valve
Size Range: DN15 to DN600
Pressure Rating: PN1.0 to PN10 MPa
Temperature Range: -60°C to 350°C
Actuator: Self-operated actuator
The Self Operated Control Valve provides stable pressure or tank protection control without relying on an external power supply for standard self-operated service. It responds directly to process pressure changes, helping protect storage tanks, reduce emissions, and maintain reliable operating pressure in blanketing, venting, and regulating applications. It is suited for projects comparing Self Operated Control Valve and automatic pressure regulating valve solutions.
