Check Valve, Pilot-to-Open
SAE 10-Cartridge - 420 bar
RP10A-01
60 l/min
420 bar
The RP10A allows ow from port 2 to
1 and blocks ow from port 1 to 2 until
sufcient pressure is present at port 3 to
permit ow.
Features
Exposed surfaces zinc-plated and corrosion proof
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
Low pressure drop due to CFD optimized ow path
Spring return at pilot stage for safe valve operation
Quick response
Low leakage design
Optional sealed pilot
