EPV10 - Proportional Valve
Proportional uni-directional poppet, flow control valve
Up to 30L/min (8 USgmp) • 350 bar (5000 psi)
Description
This is a uni-directional
proportionally controlled,
normally closed poppet valve.
It is ideal for lowering circuits
controlling the speed of
movement with low leakage
when closed.
Operation
In the de-energized condition,
blocked from port 2 to 1 with
no reverse flow permitted.
When energized, flow is
allowed from port 2 to port
1 in direct proportion to the
current applied to the
solenoid coil.
Features
Hardened, ground and honed
working parts to limit leakage.
IP69K Tough coil compatibility.
Continuously rated. Compact
design with low pressure drop.

WARNING
When using the
“Screw Type” over-
ride, care must be taken to
return the override back to its
neutral position before activat-
ing the valve. Failure to take
this precaution may result in
personal injury or damage to
the machine.
