hydraulicdirect-operatedplug

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.
