2-Way Poppet
SVP08-NCF
OPERATION
This is a normally-closed, pilot-operated, poppet-style 08-size solenoid
valve. When de-energized, the SPV08-NCF acts as a check valve, allowing
ow from port 1 to port 2, and blocking ow from port 2 to port 1. When
energized, the valve’s poppet is shifted and allows restricted ow through
the orice from port 2 to port 1. This valve is available with optional lter
and with pull-type manual override.
APPLICATIONS
The SVP08-NCF is designed to function as load holding or blocking valve
in applications where low internal leakage and various bleeding ows
are required in two dierent positions. In load holding applications, the
circuit should be designed so that the de-energized state is the position
that is holding the load. When it is energized, a load lowering function
will be achieved via a non-compensated orice. Example applications
include scissor & telescopic manlifts, which use a single-acting cylinder
for raising and lowering of the platform. The valve has an additional
(optional) threaded pull-type override for emergency lowering via a wire
cable or a knob handle.
