PILOT LATCH
PORT
Pressure applied to the pilot latch port will not cause the pilot
chamber to be pressurized until the knob is manually pulled
out. Pilot pressure will then hold the valve open to ow against
the spring. If the pilot pressure drops below 7 psi (0.5 bar) the
spring will shift the valve to close the ow, and even if the pilot
signal is restored, the valve will remain closed until the knob is
manually pulled out.
Valves provided with the manual latch feature can be latched in
the actuated position (open to ow) when there is no pilot pres-
sure, by pushing the manual latchpin and holding it in while the
knob is pulled out and released. To release the manual latch,
pull the knob or apply a pilot signal.
Valves provided with a pressure indicator will appear red (black
character “R” is also visible) when the pilot chamber is not
pressurized. The pilot chamber cannot be pressurized until the
knob is pulled out at which point the indicator will appear green
(black character “G” is also visible). If the pilot signal is then
lost the spring will return the valve to close the ow and the
indicator will appear red (R).
