Operation Alternatives

Electrically Tripped Valves move to latched position when the solenoid is de-energized, trips when they receive a continuous or momentary (at least 0.3 seconds) electrical signal. When tripped, they can be manually cycled open/closed, but must be reset when the solenoid has once again been de-energized.

No Voltage Release Valves move to latched position when the solenoid is energized, trips when de-energized. When tripped, they can be manually cycled open/closed, but must be reset when the solenoid has once again been energized.

Free Handle Valves move to latched position when the solenoid is energized, trips when de-energized. They cannot be manally cycled open/closed when de-energized. They can be manually cycled open/ closed or reset only when energized.
