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.

PROPORTIONATING SOLENOID VALVES

pressure drop

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.
