Relief Valves
When selecting a relief valve for a specific application, consideration should be given to the following
Direct operated poppet types – RV1 and RV10 Suitable for continuous duty with reliable fast response, the RV10 being a low pressure, low cost option. These
valves are also suitable for piloting the DPS2 logic elements.
Pilot operated poppet type with reverse freeflow check – RV2 Use as a service line relief where anticavitation make-up is required. It may also be applied as
an internally piloted counterbalance valve in a service line.
Direct operated poppet type, differential area models – RV3 and RV8 Sometimes termed a “differential area relief valve”. A fast acting valve, highly tolerant of contaminant
and providing an alternative flow path, frequently beneficial in manifold layout. Utilized in CRV3 cross-line relief packages.
Pilot operated spool type – RV5 and RV11
