Amico Automatic Cryogenic Liquid Solenoid Manifold - Manual (Page 8)

PRESSURE TRANSDUCERS
The Pressure Transducer senses the bank pressure and transfers information to
the display board to indicate the In-Use, Reserve & Empty mode. There are two
transducers in the manifold cabinet, one for the left bank cylinder and one for the
right bank cylinder.
NOTE:
Flow capacity depends on the amount of liquid containers and type of tanks/containers used. For Oxygen the average
flow per liquid tank/container is 350scfh. Flow capacity is increased with additional containers. For higher flow
requirements an external vaporizer (supplied by others) is necessary.

Description of Parts
SOLENOID VALVE
The Solenoid valve is 12 VDC, normally open and is located between the Liquid tank/
Dewar and the Line regulator. The Solenoid is logically controlled by the micro display
board with the bank In-Use being normally opened and the reserve/secondary being
held normally closed.
CHECK VALVE
A Check valve is provided upstream of each solenoid to prevent back flow while
servicing a bank.
MAIN LINE SOURCE VALVE
A 3/4” (19.05mm) isolation valve with a locking handle, supplied with the manifold
should be installed on top of the manifold connecting to the main supply line.
