Product Description

HydraForce RV58-20B-0-P-46 Pilot-Operated Relief Valve

The HydraForce RV58-20B-0-P-46 is a high-capacity, pilot-operated, spool-type hydraulic relief valve. Designed for integration into manifold systems using the VC58-2 cavity, it provides precise pressure limiting by diverting excess flow from the inlet (port 1) to the tank (port 2) when the pressure at port 1 exceeds the valve’s setting. This model features a screw adjustment mechanism which is factory preset (‘P’) within the specified pressure range (’46’), and utilizes Buna-N seals (‘0’). It is intended for applications requiring stable pressure control and protection against overpressure conditions in high-flow hydraulic circuits.
