MSV12-12 - Manual Push Valve
Push and twist directional control valve
38 L/min (10 USgpm) • 350 bar (5000 psi)
Description
This is a manually operated
high pressure push and twist
type 2 position 3 ported
directional control valve. Ideal
for isolating a system until flow
is required.
Operation
In the normal position, the
valve allows flow from port 1 to
port 2 while port 3 is blocked.
In the actuated position, flow is
allowed from port 3 to port 1
while port 2 is blocked.
Features
Hardened, ground and honed
sleeve and spool for low inter-
nal leakage. Detent allows
valve to be fixed in position.
Working Pressure 350 bar.
