PREPARATION and OPERATION
Prior to connecting gas/liquid flow lines inspect all parts of the
piping system including ferrules and fittings for dust or other
contaminants. Be sure to observe the direction of flow as indi-
cated by the arrow on the front of the valve when connecting
the fluid flow system to be monitored.
Insert tubing into the compression fittings until the ends of the
properly sized tubing home flush against the shoulders of the
fittings. Compression fittings are to be tightened according to
the manufacturer's instructions to one and one quarter turns.
Avoid over tightening.
Once installed inline with the gas or liquid to be controlled,
apply a variable DC power source at the two solenoid wires to
proportionally open and close the solenoid valve (there is no
polarity). The valve is set to begin opening at approximately 5
VDC. They can also serve as "on off" valves (valves are not
guaranteed for absolute closure). Optional PSV-D DRIVER
MODULE is available when use of a 0 to 5 VDC or 4 to 20 mA
reference control signal is desired. Contact your distributor or
Aalborg7 for more information.

PSV Proportionating Solenoid Valves are uniquely designed
to respond to variable power inputs (0-30 VDC) to regulate
flow of liquids and/or gases proportionately. For added safety
PSV valves are normally closed (NC) when de-energized.
