Alcon® a manufacturer of solenoid valves and subsidiary of ITT Corp., has released an energy efficient solenoid valve for general purpose markets. A standard two way normally closed solenoid valve must be energized continuously to remain open.

The reciprocal is true for normally open valves. However, constant draw to operate the solenoid drains batteries and consumes more energy than necessary. ITT- Alcon's latching valve operates using a 50 millisecond pulse, eliminating the constant energy draw.

This means that periods of prolonged valve inactivity require no power. Any application requiring infrequent valve switching would be a prime application for this type of energy efficient valve.
