The Hydraforce RVCV56-20A-0-N-30/ (5612541) is a precision-engineered screw-in, cartridge, direct acting poppet relief valve with an integrated reverse flow check valve. Designed for demanding hydraulic circuits, this versatile component functions as both a pressure limiter and regulator, ensuring fast response, low hysteresis, minimal leakage, and low pressure override. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 displaces the poppet from its seat, with relief flow discharging to port 2. The reverse flow feature allows fluid to pass from port 2 to port 1 when the differential pressure exceeds the check spring value. This valve can handle a maximum pressure of 420.6 bar (6100 psi) at port 1 and features adjustments that prevent springs from going solid. With proof and burst pressures reaching up to 482.6 bar (7000 psi) and 965.3 bar (14000 psi), respectively, this robust valve is built for durability with hardened spool and cage components that ensure longevity and fast response to pressure surges. The adjustable pressure range spans from 137.9 to 420.6 bar (2000 to 6100 psi), with crack pressures defined at a minimal level of 0.34 bar (5 psi). The valve supports flow ratings of up to 113.6 lpm (30 gpm) from port 1 to port 2 and up to 174.1 lpm (46 gpm) in reverse. Operating fluid temperature ranges vary depending on seal type: -40 to 100 \u00b0C with buna N seals, -26 to 204 \u00b0C with viton seals, and -54 to 107 \u00b0C with polyurethane seals. Suitable for mineral-based or synthetic fluids with lubricating properties, it accommodates a fluid viscosity range of 7.4 to 420 cSt while maintaining a maximum operating contamination level of ISO cleanliness code of up to18/16/13 per ISO4406 standards.
