RV3-10 - Relief Valve
Poppet, direct acting, differential area
76 L/min (20 USgpm) • 250 bar (3600 psi)
Operation
This valve remains closed
from port 2 to 1 until the
predetermined setting has
been reached at port 2.
The pressure acts on the
differential area between the
seat and the seal diameter on
the poppet.
Features
Hardened and ground work-
ing parts. Low leakage poppet
design. High flow rate for a
compact cartridge.
Performance DataSectional View
Description
This is a fast, direct acting
differential area screw-in
cartridge relief valve. The valve
is ideal for the protection
against shock pressures that
can damage actuators.
