Description & Features


CV5100 self-operated pressure regulator is a spring loaded, direct operated pressure regulator. Regulators feature proportional self-operating by the process medium and stabilize constant pressure value of the valve’s inlet or outlet. Valve is single seated plug structure for tight shut-off. Pressure proportional control range: from 3KPa to 3000KPa, the operating temperature down to -48°C and up to 300°C. 


Modular design in common: easy to change regulators’ regulating types (downstream or upstream pressure control), different pressure control range and operating temperature by replacement of extremely few parts.
