ESV1-10-C - Proportional Valve
Proportional flow control, normally closed, poppet
Up to 70 L/min (18.5 USgpm) • 210 bar (3000 psi)
Description
This is a 2 way 2 position,
pilot operated poppet type,
normally closed, proportional
flow control screw in cartridge
valve. Ideal for lowering cir-
cuits or in conjunction with
pressure compensators to pro-
vide proportional flow control
to any actuator.
Operation
In the de-energized position,
this valve blocks flow from port
2 to port 1and free flow is
allowed from port 1 to port 2.
In the energized position, flow
from port 1 to port 2 is restrict-
ed while free flow is allowed
from port 2 to port 1. The valve
flow is proportional to the cur-
rent 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.
