Model 390-07/3690-07 - Electronic Pressure Reducing Valve with Manual Hydraulic Bypass
The Cla-Val Model 390-07/3690-07 Electronic Actuated Pressure Reducing Valve with Manual Hydraulic Bypass combines precise control of field proven Cla-Val hydraulic pilots and simple, remote valve control. The Cla-Val Model 390-07/3690-07 Pressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure regardless of changing flow rate and/or varying inlet pressure.
This valve is ideal for pressure management because it can be programmed to minimum night time and optimum daytime pressures. This set-point scenario helps to prevent the pipeline from being over-pressurized during times of lower demand and makes the pipeline less susceptible to background leakage and pipe bursts.
Internal continuous electronic monitoring of actuator position results in virtually instantaneous position change with no backlash or dithering when control signal is changed. In the event of a power or control input failure, the CRD-33 pilot remains in hydraulic control virtually assuring system stability under changing conditions. During SCADA startup and maintenance the manually-adjusted CRD pilot control allows automatic hydraulic valve operation when no electric power is available for CRD-33.
