FPR - Check valve
Guided poppet line mounted
Up to 310 L/min (82 USgpm) • 350 bar (5000 psi)
Description
A range of line mounted valves
for convenient installation into
hydraulic circuits. Valves allow
ow at a low pressure drop
(from 0.5 bar, 7 psi) in the free
ow direction and prevent ow
in the reverse direction. The
range extends from 1/4” BSP
to 1 1/2” BSP (12 liters/min 3
US GPM to 310 min/min, 82
US GPM) nominal ow with
cracking pressures from 0.5 to
5 bar (7 to 72.5 psi).
Operation
These are in line check valves.
Free ow is allowed from
port 1 to port 2 when the inlet
pressure rises higher than the
crack pressure.
Flow is prevented between
port 2 and port 1 by the
poppet resting on the seat
within the body.
Features
All steel construction with
hardened and precision
ground poppet gives excellent
ow capability and shut-off
characteristics with good
tolerance to particle (dirt)
contaminated uid.
