Direct Acting, Poppet Type, SAE-08 Cartridge – RP08A-01

Direct Acting, Poppet Type, SAE-08 Cartridge RP08A-01

The pilot-to-open check valve RP08A is a direct-acting, spring-loaded poppet valve.

There is free flow from port 2 to port 1. In the opposite direction, the pressure of the poppet onto the seat blocks the flow. If a sufficiently high control pressure builds at port 3, it will lift the poppet from the valve seat. Then, oil will flow from 1 to 2. The necessary pilot pressure at port 3 is dependent on the pressure across port 1 and 2.

See datasheet for drawings, dimensions, model code, etc…


  • Corrosion protection of external surfaces through blue zinc-plating or thermo-chemical Nitrotec coating (black)
  • Hardened and ground internal valve components to ensure minimal wear and extended service life
  • Low pressure drop due to CFD optimized flow path
  • Spring return in the pilot stage for safe valve operation
  • Quick response
  • Low leakage design
  • Optional pilot piston seal
