ESV1-12-O - Proportional Valve
Proportional flow control, normally open, poppet
Up to 104 L/min (27.3 USgpm) • 210 bar (3000 psi)
Description
This is a 2 way 2 position,
pilot operated poppet type,
normally open, proportional
flow control screw in cartridge
valve. Ideal for lowering
circuits or in conjunction
with pressure compensators
to provide proportional 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 working
parts to give long life and very
low leakage. IP69K Tough coil
compatibility, continuously
rated. Compact design with
low pressure drop.
