Product Information PRESSURE VALVEDirect-Acting,Relief Valve (High Pressure) Type: HRV09-P0 Max. operating pressure: 350 bar (5000 psi) Proof pressure: 525 bar (7600 psi) Flow: 40 L/min Description A screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve, applied as a pressure limiting device in hydraulic circuits requiring fast respond and low hysteresis. Operation The HRV09-P0 blocks flow from © to © until sufficient pressure at © is applied to force the spring-opposed poppet from its seat. The HRV09-P0 offers fast response to load changes in hydraulic circuits. Technical Data Proof pressure Flow See performance chart Internal leakage 0.25 ml/min(5 drops/min) max. at 80% of normal setting Crack (Set) pressure defined Bar evident at 7.6 L/min attained Reseat pressure Nominal 80% of crack pressure Standard spring ranges Factory default preset value: 50% of rated pressure (See chart 1) Temperature range -40°C ~ 120°C with standard buna seals -26°C ~ 204C with fluorocarbon seals -54C ~ 107C with polyurethane seals Filtration Fluid Installation Max. nominal value: 10 um (NAS 8), ISO4406 19/17/14 Mineral based or synthetics with lubricating properties at viscosities of 7.4 ~ 420 cSt(50 ~ 2000 ssu) No restriction Cavity tool (Chart 1: Standard Spring Range)

Direct-Acting,Relief Valve Product Information • Fast and smooth response to pressure changes. • Positive stops prevent springs from going solid. • Compact size. • Adjustments cannot be backed out of the valve. • Industry common cavity. • Hardened poppet and cage for long life. • Unique poppet structure designed to improve the pressure stability.
