Owner's manual

Toggling the HIGH/LOW signal on and off will allow for activating and
deactivating the solenoid valve. Remember: If the TTL signal line is con-
nected, the valve will only function if the appropriate logic input is applied.
e.5 FSV Proportionating Solenoid Valves
e.5.1 FSV Preperation and Operation
Prior to connecting gas/liquid flow lines inspect all parts of the piping sys-
tem including ferrules and fittings for dust or other contaminants. Be sure
to observe the direction of flow as indicated 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 vari-
able 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 FSV D
DRIVER MODULE is available when use of a 0 to 5 VDC or 4 to 20 mA
reference control signal is desired. Contact Omega7 for more information.
FSV 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 FSV valves are normally closed
(NC) when de-energized.
