PTS16-12 - Pilot to Shift Valve
Pilot operated, directional control valve
76 L/min (20 USgpm) • 350 bar (5000 psi)
Description
This is a 4-way, 2 position,
remotely pilot operated
directional control valve ideal
for reversing a function when
the pilot pressure is applied or
lost.
Operation
This valve allows flow
between ports 1 and 2 and
ports 3 and 4 until sufficient
pressure has been applied at
port 5 and the spring bias is
overcome. At that time, flow is
Performance Data
directed between ports 1 and
4 and ports 3 and 2. During
the cross-over transition, all
ports are blocked. The spring
chamber for this valve is
vented internally to port 1.
Features
Hardened, ground and honed
sleeve and spool for low
internal leakage. Working
pressure 350 bar.
