Eaton Hydraulic Screw-in Cartridge Valves (SiCV) E-VLSC-MC001

Operation
Pressure on the valve port
2 causes the poppet to lift
against the spring force,
allowing the ow to the
cylinder port 3. Reverse ow
is prevented by the poppet
reseating.
Pressure applied to the
pilot port 1 will overcome
the cylinder port pressure
and lift the poppet from its
seat, allowing ow from the
cylinder to valve port.
Features
Hardened and ground poppet
gives excellent ow capability
for valve size, positive
sealing and long working
life. Cartridge construction
allows installation in actuators,
manifold blocks and Hydraulic
Integrated Circuits. Fits the
same cavity as the overcenter
valves of a similar size.

SPC2-10 - Check valve
Pilot-to-open, poppet type
23 L/min (6 USgpm) • 210 bar (3000 psi)
Description
Pilot check valves allow ow
to pass in one direction, with
a low pressure drop, then
prevent reverse ow until pilot
pressure is applied. There
are many applications for this
valve type, the most common
being to lock and hold a
cylinder, or another hydraulic
actuator, in position.
These valves are ideally
suited for tting directly into
a cylinder, giving economy of
installation, direct control of
cylinder movement and ease
of servicing.

D - Port 3 to 2 (piloted open)
Warning
Do not use Single Pilot
Check Valves in load holding
applications where either
overrunning loads are possible
or load release speed is
critical. Failure to observe
these guidelines may result
in bodily injury or damage to
equipment.
