PTS3-20 - Pilot to Shift Valve
Pilot operated, directional control valve
265 L/min (70 USgpm) • 210 bar (3000 psi)
Description
This is a 3-way 2 position,
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 3 and 4 while
blocking port 2 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 2 and port 3
while blocking port 4. During
the cross-over transition, all
ports are blocked. The spring
chamber for this valve is
vented to port 4.
Features
Hardened, ground and honed
sleeve and spool for low
internal leakage.
