Eaton Hydraulic Screw-in Cartridge Valves (SiCV) E-VLSC-MC001
-E—January 20
18 www.eaton.com
Operation
The valve remains closed until
the spring bias is reached
at port 1 at which time the
poppet lifts of the seat and
allows ow from port 1 to port
2. in the other direction the
valve is closed.
Features
Cartridge design with
machined seats and precision
ground balls gives excellent
ow reseat characteristics.
Installation into the 2-port 7/8"
UNF cavity gives easy tment
and serviceability
.

Sectional view
Description
These cartridge check valves
allow ow at a low pressure
drop, with cracking pressure
from 0.5 to 7 bar (7 to 100 psi)
in the free ow direction and
close to prevent ow in the
reverse direction.
They t into simply machined
cavities and are therefore ideal
for installation into custom
designed Hydraulic Integrated
Circuits, manifold blocks and
other hydraulic equipment.
