Applications
On/Off Check Valve
Will hold valve closed in one condition
and serve as a check valve in the other
condition.
Senses the greater of two pressures
between the X port & the A port. The X
port should be connected to the B port
(side of logic valve), & the Z1 port
should be connected to the A port (nose
of logic valve).
By using a standard D03 directional
control with flow from P to A in the de-
energized condition, the shuttle will use
the greater pressure to hold the valve
closed. Energizing the solenoid prevents
the shuttle from sensing the Z1 pilot,
thereby establishing free flow from A to
B & a check valve function from B to A.
