RV08-20

Description

RV08-20X is a screw in, cartridge style, direct acting, poppet type, hydraulic relief valve intended for lower flow circuits requiring low internal leakage

Operation

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

• 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.

Notes

Supersession: Existing and new applications.

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
