Operating and Maintenance Instructions for
Quantum Falcon Solenoid Valve
General Description
The Falcon solenoid valve incorporates elastomer static seals through which a shaped spool moves and are manufactured for 3 or 4way
operation. 3 way is normally used for pilot control of the other relay valves or for the operation of single acting cylinders. 4way is normally
used to control the action of double acting cylinders.
The seal spacer assembly forms individual annular chambers opposite each valve port and the grooved spool either closes or allows flow
between adjacent chambers, hence the position of the spool determines which ports are open or closed.
The spool is moved by way of a manually or mechanically operated mechanism normally against a return spring. Operation may be by
application or removal of a pilot air supply acting as a pilot piston. This form of control is utilized for electrical actuation where integral
solenoid valves control the pilot air supply.
Optional Features
N - No-Voltage Release (Latching)
With the coil first energized, the palm button is then manually moved and latched. The inward movement of the palm button causes the
valve to shift. When the coil is de-energized, the palm button and latching mechanism are automatically tripped, allowing the valve to
return to its original position. (1.2 Cv Valves only) See Fig. 1
R - No-Voltage Release (Non-Latching)
With the coil first energized, the palm button is then manually moved. The inward movement of the palm button causes the valve to shift.
When the coil is de-energized, the palm button automatically returns to its original position. (1.2 Cv Valves only) See Fig. 2
L - Manual Locking Override
Manually depress palm button and rotate clockwise for maintained con-
dition, must manually disengage to return to original position. See Fig. 3
M - Momentary Override
Spring return momentary pushtype, must hold in to actuate. See Fig. 4
E - External Pilot
The 1/8”NPT external pilot connection requires a separate auxiliary
pressure line to the valve. This feature should be used when the con-
trolled pressure is below the minimum 45 psi operating pressure.
H - Hex Drive Maintained Override
Insert allen key in hex head screw and rotate clockwise (4-5 turns) to
shift spool. Valve will stay put until hex head screw is rotated counter
clockwise (4-5 turns) back to original position. See Fig. 5

Specifications
Operating Pressure: 45-120 PSIG
Operating Temperature: -20€C to +85€C
Operating Media: Non Lubricated Filtered Air to 20 Microns
Field Wiring
Complete the electrical wiring in accordance with local and National Electrical Codes. The ground wire should be secure under the green
screw. Check all screws for tightness. If the installation is in a hazardous area, all electrical leads must be sealed with an approved com-
pound, in accordance with local and National Electrical Codes unless the switches are hermetically sealed. (NEC 5051-5)
Always check the nameplate to make sure the approval ratings coincide with the application.
CAUTION: To prevent ignition of hazardous atmospheres, replace cover before connecting the electrical circuits.
Keep cover tightly closed when in operation.

(Air Line) Installation Considerations
Air Mains and lines should be large enough to avoid excessive pressure loss under conditions of maximum flow. Air lines should be
installed with as few restrictions as possible if the cost of compressed air is to be kept to a minimum. Sharp turns in piping should be
avoided for more effecient air flow and economical air power. It is advisable to pitch the mains in the direction of air flow so that both grav-
ity and air flow will carry the water to traps or water legs located at frequent intervals.
To help in preventing condensed moisture from reaching the point of usage, down pipes should never be taken directly from the bottom
of air pipes or mains. Connection should be made at the top of the main and a long radius return bend used.

AIR FLOW
Pipe sizes are normally determined on semi empirical lines, basis for selection being an acceptable pressure drop e.g. not more than
10% of the applied pressure. In sizing pipes, consideration should be given to likely future demands, as a system will be inefficient if the
demand outgrows the supply. It is always better to over size mains as this will reduce air velocity and make water separation more
effective.
AIR SERVICE EQUIPMENT
The importance of proper filtration (20 Micron) and lubrication of the air supply to pneumatic equipment can never be over-emphasized
as a means of decreasing friction and preventing corrosion and wear due to moisture and abrasive solids being present in the air supply.
At higher pressures than recommended, pneumatic equipment can wear excessively with no significant increase in output and com-
pressed air is consequently wasted.
There is much to be gained, therefore, from providing pneumatic equipment with serviced air by including suitable air line filters, pressure
regulators and lubricants in the installation.
TUBES AND FITTINGS
The use of copper,stainless steel, nylon or polyethylene tube is recommended for piping up air circuits and equipment. As a general rule,
pipe threaded fittings should not be assembled to a specific torque because the torque required for a reliable joint varies with thread qual-
ity, port and fitting materials, sealant used, and other factors. The suggested method of assembling pipe threaded connections is to
assemble them finger tight and then wrench tighten further to a specified number of turns from finger tight. The assembly procedure
given below is for reference only, the fitting should not be over tightened for this will lead to distortion and most likely, complete valve fail-
ure.
1. Inspect port and connectors to ensure that the threads on both are free of dirt, burrs and excessive nicks.
2. Apply sealant/lubricant or Teflon tape to the male pipe threads. With any sealant tape, the first one or two threads should be left uncov-
ered to avoid system contamination.
3. Screw the connector into the port to the finger tight position.
4. Wrench tighten the connector aproximately 1 - 2 turns (to seal) from finger tight. again this is only reference - the fitting should NOT be
over tightened.
SPECIAL NOTICE
Delrin valve bodies are fitted with hellicoils therefore an extra effort should be made NOT to overtighten pipe fittings or retaining screws
(.5 - 1 turns from finger tight to seal). Overtightening will result in valve failure or pull hellicoils from valve body.
MAINTENANCE
Routine maintenance is usually confined to the periodic replenishment of Dow Corning III lubricant or equivalent to spool and spring.
