Applications
Dump Valve or ON/OFF valve
Can be used as a dump valve by
Connecting X to the B port
(side of logic valve) &
connecting Y to drain. The
diagrams to the right show the
two different plug options. Plug
option #1 will allow the valve to
dump in the de-energized state,
& Plug option #2 will allow the
valve to dump in the energized
state.
Note: If port A is connected to a working
port, then connecting X to the B port, as
shown above, does not prevent pressure at A
from overcoming the forces acting to keep the
valve closed. Flow could occur from A to B.
To prevent this, use a separate pilot pressure
for X.
