The Hydraforce 5612542.M420 (5612542.M420) is a screw-in, cartridge, direct acting poppet relief valve with an integrated reverse flow check valve. This device is specifically designed for use as a pressure limiter and regulator in demanding hydraulic circuits that require rapid response, minimal hysteresis, low leakage, and low pressure override. The RVCV56-20X model effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to displace the poppet from its seat, allowing relief flow to discharge to port 2. Additionally, it facilitates reverse flow from port 2 to port 1 when the differential pressure between these ports surpasses the check spring value. Engineered for durability and performance, this valve features a hardened spool and cage for extended lifespan and provides fast, smooth responses to pressure surges. It can withstand a maximum pressure of up to 420.6 bar (6100 psi) at port 1. The design ensures that adjustments cannot be backed out of the valve or allow springs to go solid, maintaining consistent operation under high-pressure conditions.
