G relief valve RV08-P0

hydraulicstandardcompact

A screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for low flow rate hydraulic circuits requiring low internal leakage. Operation The RV08-P0 blocks flow from ①to② until sufficient pressure at ① is applied at ➀ to force the poppet from its seat. The RV08-P0 responds fast to load changes in typical hydraulic circuits requiring low internal leakage. *Note: Back pressure at ② will increase pilot pressure required at ① to shift, at a ratio of 1:1. The RV08-0 may be used in cross-over relief applications (back pressure on ②) with the use of the “C” double back-up ring seal option. Features 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. Flow: See performance chart Internal leakage: 0.25 mL/min (5 drops/min) max. 75% of norｍinal setting Crack(set) pressure defined: Bar evident at 1 L/min attained Reseat pressure: Nominal 80% of crack pressure Standard spring ranges: Factory default preset value: 50% of rated pressure Fluid: Mineral based or synthetics with lubricating properties at viscosities of 7.4~420 cSt (50-2000 ssu) Installation: No restriction Cavity: VC08-2 Cavity tool: T/H08-2RC-T-G (Rough), T/H08-2FM-T-G (Finishing) Seat kit: SK08-2N -B
