EATON Vickers Screw-In Cartridge Valves V-VLOV-MC001-E4 September, 2007G-30
Description
The SPC1-10 is an in-line
housing type, pilot-to-open
check valve.
SPC1-10
Single pilot check valve
Operation
This valve allows flow from
the valve port to the cylin-
der port when the spring
bias is overcome.
Flow is blocked from the
cylinder port to the valve
port until sufficient pilot
pressure is applied at the
pilot port.

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.
