The Hydraforce 5612688V (5612688V) is a sophisticated screw-in, cartridge-style direct acting poppet relief valve that integrates a reverse flow check valve. Designed for use in demanding hydraulic circuits, this valve excels as a pressure limiter and regulator, providing fast response times with minimal hysteresis and leakage. It features low pressure override capabilities and supports reverse free flow, making it ideal for applications requiring precise pressure control and efficient flow management. The RVCV56-20X 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 surpasses the check spring value. This robust component can withstand a maximum pressure of 420.6 bar (6100 psi) at port 1, ensuring durability under high-pressure conditions. The design includes non-backout adjustments and prevents springs from becoming solid, enhancing operational reliability. Moreover, the hardened spool and cage contribute to the valve's longevity by offering resistance against wear and tear while ensuring smooth responses to sudden pressure surges.
