SV12A/B-12-3 - Solenoid Valve
3-way, 2-position, spool type solenoid valve
Up to 34 L/min (9 USgpm) • 350 bar (5000 psi)
Description
This is a 3-way 2-position, high
pressure, direct acting, spool
type solenoid valve. This valve
can be used in applications
requiring separate pressure
and tank lines, such as a single
acting cylinder or any other
application where a three way
two position solenoid valve is
needed.
Operation
In the de-energized position
this valve allows flow from
port 1 to 3 while port 2 is
blocked.
In the energized position flow
is allowed from port 2 to port
1 while port 3 is blocked.
Features
Hardened, ground and honed
working parts to limit leakage.
IP69K Tough coil compatibility.
Continuously rated. Compact
design with low pressure drop.
Rated pressure on all ports.
Working pressure 350 bar.
Pressure Drop
Cartridge only
