RV2-10 - Relief Valve
Poppet, pilot operated with reverse flow check
12-114 L/min (3-30 USgpm) • 350 bar (5000 psi)
Operation
When the inlet reaches the
valve setting, the pilot section
opens, causing a small flow
across the orifice in the
poppet.
The subsequent pressure drop
moves the poppet, opening
the valve, allowing relief flow
to tank.
Features
Very low pressure rise for
any increase in flow giving
accurate pressure control.
Hardened working parts give
long, reliable, trouble-free
life. Cartridge construction
giving maximum flexibility in
mounting.

Description
This is a pilot operated relief
valve with an integral free
flow check designed to limit
pressure in a system. Good for
continuous duty and accurate
pressure control with constant
or varying flows With integral
reverse flow check.
