Hydraforce RV08-20A-0-N-18 Pressure Controls, Relief Valve, Direct Acting, Poppet Type
SKU: RV08-20A-0-N-18
Hydraforce Part Number: RV08-20A-0-N-18
Seal Kit: SK08-2X-B (X=seal option)
RV08-20X is a screw in, cartridge style, direct acting, poppet type, hydraulic relief valve intended for lower flow circuits requiring low internal leakage.
RV08-20X blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the spring opposed poppet off its seat.
- Adjustments cannot be backed out of the valve.
- Variety of pressure adjustment options including non-adjustable factory preset.
- Adjustments options A, B, and C: positive stops prevent springs from going solid.
- Optional spring ranges to 248 bar (3600 psi).
- Rapid response to pressure changes.
- Optional bi-directional pressure (requires bi-directional pressure seal option).
- Compact size.
RVD58-20 Is our best-in-class relief valve and can functionally replace this valve in most applications. We strongly encourage you to consider this newer alternative.
Considerations:
- Comparable pressure and flow ratings
- Comparable response rate
- Better pressure rise characteristics
- Smaller size
- No dynamic seal
- Competitive cost
- VC08-2B cavity variation is required. Some manifolds may allow drop-in replacement.
- Assistance is available to evaluate your application
