Pilot operated, balanced piston relief valve
Capacity:
50 gpm (200 L/min.)
Functional Group:
: Cartridges : Relief : 2 Port : Pilot Operated, Balanced Piston
Model:
RPGC
Product Description
Pilot-operated, balanced-piston relief cartridges are normally closed
pressure regulating valves. When the pressure at the inlet (port 1)
reaches the valve setting, the valve starts to open to tank (port 2),
throttling flow to regulate the pressure. These valves are accurate,
have low pressure rise vs. flow, they are smooth and quiet, and are
moderately fast.
Technical Features

Will accept maximum pressure at port 2; suitable
for use in cross port relief circuits. If used in cross
port relief circuits, consider spool leakage.

Main stage orifice is protected by a 150 micron
stainless steel screen.

Not suitable for use in load holding applications
due to spool leakage.

B
ack pressure on the tank port (port 2) is directly
additive to the valve setting at a 1:1 ratio.

All 2-port relief cartridges (except pilot reliefs) are
physically and functionally interchangeable (same
flow path, same cavity for a given frame size).

Stainless steel cartridge options P or W are
intended for use within corrosive environments
with all external components manufactured in
stainless steel or titanium. Internal working
components remain the same as the standard
valves.

Incorporates the Sun floating style construction to
minimize the possibility of internal parts binding
due to excessive installation torque and/or
cavity/cartridge machining variations.
