RV1-12 - Relief Valve
Poppet, Direct Acting
114 L/min (30 USgpm) • 350 bar (5000 psi)
Operation
This valve remains closed from
port 1 to port 2 until the pre-
determined setting has been
reached at port 1.
The poppet is unseated and
allows flow out of port 2.
Features
Hardened and ground work-
ing parts. Low leakage poppet
design. High flow rate for a
compact cartridge.
