PTS1-20 - 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 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.
