Legend
AT..Air pressure tank
CK..Check valve
DR..Standard drain to sewer
DRV.Drain valve, normally open
E...Exhaust
NC..Normally closed pilot valve
NO..Normally opened pilot valve
NV..Needle valve
N10.Pressure is applied to actuator to open steam when
pilot valve is energized.
N11.Pressure is applied to actuator to close drain valve
when pilot valve is energized.
N12.Pressure is applied to actuator to close reuse drain
when pilot valve is de-energized.
N13.Pressure inflates pushdown cushions when pilot
valve is energized. De-energized cushions exhaust
through quick releases.
PD..Pushdown
PG..Pressure gage
PLF.Pushdown left front
PRR.Pushdown right rear
PR..Pressure regulator, setting 40psi
RDR.Optional drain to reuse
