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.

Pressure and Flow Graphs
Vektek’s new PRV Control Block is the ideal answer to this type of operational dilemma. When this control block is implemented under a 3-Position 4-Port directional control valve, the pump pressure setting can be set up to 5,000 psi. Pressure can then be reduced at the individual circuit by the valve itself. Since the PRV Control Block is DO3 mounted it can be used on the pump stack or as a remote mounted valve.
Dual valve configuration
Also available in single valve configuration
NOTE: Maximum system flow rate is 1.5 gpm (346.5 cu. in. per minute) for all VektorFlo® special function valves.
