ELECTRICAL DATA
Volt-ampere (VA) ratings All solenoid, circuit board, and motor ratings are shown in Table I. Total connected load on any valve should not exceed 2000 VA. This limitation includes the maximum consumption shown in Table I plus the VA consumption of external equipment powered by the auxiliary switches at any one time.

Switch contacts are shown with the valve shut, unpowered. Wiring shown above the terminal strip is internal. Wiring below terminal strip is external (field), as required. All wires are number-coded as shown to match terminals. Termi- nals "2" and "DC" are neutral; all others are hot.
General
All standard shutoff valves are designed for operation on 115 V 60 Hz power supply. Optional voltages, Hz, direct current, or special switches, involve extra cost and extended delivery. Specify power characteristics when ordering. A solenoid or circuit board is energized whenever valve is powered. Holding current volt-amperes are continuous once energized. Motor on any 1519 Valve is powered only during the opening stroke. The normally closed contact of a limit switch breaks motor circuit when full-open position is reached. Flow begins within 1 second of powering. Full closure is complete within 1 second after de-energizing. Supply voltage must agree with valves nameplate voltage within -15%/+10% for proper operation.
Series 1519- -X only
Standard 120 V power input is converted by a circuit board (no solenoid) to 90 V dc output to a magnetic clutch that is energized whenever valve is powered. Circuit board components also act as a time delay, allowing 1⁄10 second response lag after main power interruption (this helps avoid nuisance shutdowns).
WARNING: Do not attempt field repair of valve body, top assembly, or motor drive unit. Any alterations could be dangerous, and will void all warranties.
