Hydraforce RV08-22H-0-N-26 Directional Controls – Logic Element – Pilot to Close

SKU: RV08-22H-0-N-26

Hydraforce Part Number: RV08-22H-0-N-26

Seal Kit: SK08-2X-T, X=seal options

RV08-22X is a screw in, cartridge style, direct acting, differential area, poppet type, hydraulic relief valve for use as a pressure limiting device in more demanding hydraulic circuits requiring low hysteresis and low internal

RV08-22X blocks flow from port 2 to port 1 until sufficient pressure is present at port 2 to force the poppet off its seat.

• Adjustments cannot be backed out of the valve.
• Variety of pressure adjustment options including non-adjustable factory preset.
• Adjustment options A, B, and C: positive stops prevent springs from going solid.
• Optional bi-directional pressure (requires bi-directional pressure seal option).
• Hardened poppet and cage for long life.
• Optional spring ranges to 248 bar (3600 psi).
• Smooth response to pressure surges.
• Industry common cavity.
• Compact size.
