The Hydraforce CR08-38A-0-N-30/15 (5601720.15) is a screw-in, cartridge-style, direct-acting, bi-directional poppet type hydraulic relief valve designed to serve as a pressure limiting device in challenging hydraulic circuits. It is characterized by its low hysteresis and minimal internal leakage. The valve operates by blocking flow from port 1 to port 2 bi-directionally while consistently draining the spring chamber at port 3. When a pre-determined pressure is reached at either port 1 or port 2, the spring-opposed poppet is actuated from its seat, allowing flow through the system. This product features adjustments that cannot be backed out of the valve and prevents springs from becoming solid, ensuring durability with hardened parts for extended life. The CR08-38A-0-N-30/15 has a pressure rating of 207 bar (3000 psi) for both ports 1 and 2, and 103 bar (1500 psi) for port 3. It can withstand proof pressures up to 448 bar (6500 psi) and burst pressures up to 896 bar (13000 psi). The reseat pressure is set at 90% of crack pressure with a flow rate of 0.95 lpm (0.25 gpm). This valve supports a maximum flow rate of 30.3 lpm (8 gpm) with internal leakage capped at 0.4 ml/min at 75% of crack pressure. The operating fluid temperature ranges from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals and -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, while storage temperatures range between -40 to 70 \u00b0C (-40 to160 \u00b0F). The valve accommodates fluids that are mineral-based or synthetic with lubricating properties within a viscosity range of 7.4 to420 cSt, maintaining an ISO cleanliness level of18/16/13 per ISO4406 standards.
