ESV1-8-O - Proportional Valve
Proportional flow control, normally open, poppet
Up to 32 L/min (8.4 USgpm) • 210 bar (3000 psi)
Description
This is a 2 way 2 position, pilot
operated poppet type, normal-
ly open, proportional flow con-
trol screw in cartridge valve.
Ideal for lowering circuits or
in conjunction with pressure
compensators to provide pro-
portional flow control to any
actuator.
Operation
In the de-energized position,
this valve allows free flow from
port 2 to port 1 and restricts
flow from port 1 to port 2.
In the energized position, flow
is blocked from port 2 to port 1,
and free flow is allowed from
port 1 to port 2. The valve flow
is proportional to the current
applied to the coil.
Features
Hardened and ground work-
ing parts to give long life and
very low leakage. IP69K Tough
coil compatibility, continuously
rated. Compact design with
low pressure drop.
