The Hydraforce RVCV56-20A-0-P-45 (5612545P) is a robust screw-in, cartridge, direct acting poppet relief valve with an integrated reverse flow check valve. This component is designed for high-demand hydraulic circuits where precise pressure regulation and limiting are crucial. It offers fast response times, low hysteresis, minimal leakage, and low pressure override while allowing reverse free flow. The valve operates by blocking the 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. The reverse flow capability enables flow from port 2 to port 1 when the differential pressure exceeds the check spring value. It can withstand a maximum pressure of 420.6 bar (6100 psi) at port 1 and has a proof pressure of 482.6 bar (7000 psi) with a burst pressure of up to 965.3 bar (14000 psi). The adjustable pressure range spans from 137.9 to 420.6 bar (2000 to 6100 psi), with specific settings ensuring less than a 20% overshoot and reseat pressures at approximately 85% of crack maximum. The valve handles a maximum flow rate of up to 113.6 lpm (30 gpm) from port 1 to port 2 and up to 174.1 lpm (46 gpm) in reverse direction, maintaining internal leakage below 0.53 ml/min under specified conditions. It operates effectively across various temperatures depending on seal type, with options for buna N, viton, or polyurethane seals catering for diverse operating environments ranging from -54\u00b0C (-65\u00b0F) up to +204\u00b0C (+400\u00b0F). Its robust construction includes hardened spool and cage for durability against pressure surges, ensuring long service life in demanding applications without orientation restrictions during installation into VC16-2 variation 'a' cavities using appropriate torque specifications.
