SYMBOL: |
DESCRIPTION A screw-in, cartridge-style, direct-acting, spool-type, hydraulic pressure-regulating relief valve intended for use as a pressure limiting device for common hydraulic circuit protection. OPERATION The RV10-21F blocks flow from 1 to 2 until sufficient pressure is present at 1 to force the poppet off its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low internal leakage. FEATURES • Several pressure codes available. • Rapid response to pressure surges. • Low internal leakage. • Industry common cavity. • Hardened spool and cage for long life. RATINGS Operating Pressure: 228 bar (3300 psi) Flow Limit: Pressure Code 30: 11.36 lpm (3 gpm) Pressure Code 100: 20.82 lpm (5.5 gpm) Pressure Code 150: 24.60 lpm (6.5 gpm) Internal Leakage: 10 drops/minute max. at 85% of crack pressure Crack (Set) Pressure Defined (at 0.76 lpm (0.2 gpm): Pressure Code 30: 1.38 bar to 2.76 bar (20 psi to 40 psi) Pressure Code 100: 6.21 bar to 7.59 bar (90 psi to 110 psi) Pressure Code 150: 9.66 bar to 11.04 bar (140 psi to 160 psi) Reseat Pressure: Nominal 85% of crack pressure Standard Spring Ranges: Due to manufacturing tolerances, it may be possible to adjust the valve either lower or higher than the nominal ratings shown below. Temperature: -40° to 100°C (-40° to 212°F) with Buna N seals; -26° to 204°C (-15° to 400°F) with Fluorocarbon seals; -54° to 107°C (-65°F to 225°F) with Polyurethane seals Filtration: See page 9.010.1 Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1 Installation: No restrictions; See page 9.020.1 Cavity: VC10-2; See page 9.110_2w Cavity Tool: CT10-2xx; See page 8.600.1 Seal Kit: SK10-2x-B; or SK10-2x-B; See page 8.650.1 |
