PTS17-12 - Pilot to Shift Valve
2/2, pilot operated directional control valve
114 L/min (30 USgpm) • 350 bar (5000 psi)
Performance Data
Operation
This valve allows flow
between ports 2 and 3 until
sufficient pressure at port 1
overcomes the spring bias,
which closes both ports.
The spring chamber for this
valve is externally vented to
atmosphere.
Features
Hardened, ground and honed
sleeve and spool for low
internal leakage. Working
pressure 350 bar.
Description
This is a 2-way 2 position,
high pressure, pilot operated
directional control valve ideal
for isolating a function when
the pilot pressure is applied or
removed.
