Accessory Valves
Pressure Reducing Valve Control Block
PRV Control Blocks Control pressure independently on both the clamp and unclamp side of the fixture regardless of pump pressure setting. Eliminate the wait for full system pressure to finish cycling workholding components. For use in double or single acting systems. DO3 Mounting, use on pump stack or as a remote mounted valve. n Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum).
