Description
The HydraForce RV08-20 valve 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.
Features include:
- 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
Pressure ratings:
- Pressure rating: 275.8 bar (4000 psi), 482.6 bar (7000 psi)
- Burst pressure: 896.3 bar (13000 psi)
- Relief pressure defined: pressure evident at 0.95 litres / minute (0.25 gallons/ minute)
Note that the HydraForce RV08-20 has been superseeded by the RVD58-20 in most applications. Considerations include:
- 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.
