A screw-in, cartridge-style, pilot-operated (two-stage), spool-type hydraulic relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis.
• Adjustments cannot be backed out of the valve • Optional spring ranges to 240 bar (3500 psi) • Fast, smooth response to pressure surges • Industry common cavity • Hardened poppet and cage for long life
