Pilot Operated Relief Valves MV1-5 & MV2- DRF-5


These two-stage valves limit system pressure by directing flow to tank or the opposite cylinder port (A-B/B-A crossport types) when system pressure reaches the valve setting. Pressure control may be obtained in "A", "B" , "A" and "B" or "P" port, and pilot flow may be internally or externally drained, depending on model type. The valve pressure setting is adjustable by means of either an adjusting screw and locknut. External remote control/vent connections are available on all models except crossport relief.
