Operation: The Pressure Reducing Valve (PRV) is a Normally Open (N/O) pressure control device.The valve remains open and fluid flows freely to downstream devices (from the valve to devices) until the pressure in the valve reaches the pressure (adjustable) set-point. At the set-point pressure the valve closes, blocking further flow and pressure rise to the downstream devices. If there is a sufficient down stream pressure loss (from the valve to devices), the PRV will re-open, allowing flow to pass through the valve until the pressure again reaches the valve set-point. The PRV is designed for use in both single and double acting systems.
Once the PRV closes, it will re-open in the event of a downstream pressure loss, allowing the pressure to again build to the intended system set-point.
NOTE: Maximum system flow rate is 1.5 gpm (346.5 cu. in. per minute) for all Vektorflo® special function valves.
Excess flow voids warranty.
