PTS11-12 - Pilot to Shift Valve
Pilot operated, directional control valve
76 L/min (20 USgpm) • 350 bar (5000 psi)
Description
This is a 3-way 2 position,
high pressure pilot operated,
directional control valve ideal
for selecting a function when
the pilot pressure is applied or
removed.
Operation
This valve allows flow
between ports 2 and 3 while
blocking port 4 until sufficient
pressure has been applied to
port 1 and the spring bias is
overcome.
Performance Data
At this time, flow is directed
between port 3 and port 4
while blocking port 2. During
the cross-over transition, all
ports are blocked. 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.
