HydraForce RV08-20 Relief Valve Cartridge Direct Acting Poppet Type

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.
