SOLENOID AND PRESSURE GAUGE ASSEMBLY
WITH SUPERVISORY PRESSURE SWITCH
The solenoid/pressure gauge assembly provides an elec-
trical means (24 Vdc) of actuating the system as well as a
visual means to determine the pressure within the pilot
cylinder.
This unit includes an integral supervisory pressure switch
and is supplied with a pilot flex hose #1. The supervisory
pressure switch consists of one normally open (N.O.)
contact that changes state upon loss of cylinder pres-
sure.

PRESSURE GAUGE ASSEMBLY
WITH SUPERVISORY PRESSURE SWITCH,
P/N 38-109891-001
This unit is required for the slave cylinders to provide a
local visual means to determine the pressure within the
slave cylinder.
The pressure gauge assembly includes an integral
supervisory pressure switch, consisting of one N.O. con-
tact that changes state upon loss of cylinder pressure.
PILOT FLEX HOSE #1, P/N 38-509818-001
This 1/4-inch ID reinforced rubber flex hose has threaded
connections to allow interface between the pilot cylinder
solenoid/pressure gauge assembly and pilot manual/
pneumatic actuator. It is supplied with the pilot solenoid
assembly.

MANUAL/PNEUMATIC ACTUATOR,
P/N 38-509841-001
The manual/pneumatic actuator supplied with the pilot
completer kit is required on the pilot cylinder to manually
actuate the cylinder valve as well as to supply pressure
to actuate any slave cylinders. Interconnection between
cylinders is by means of high-pressure flex hoses.
