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.
Pilot operation
Hardened and ground working
parts to limit leakage and
extend service life. Robust
design with a 350 bar max
pressure rating.
