Valtorc can supply a model UPS9 Uninterpretable Power Supply in a NEMA 4 enclosure for those applications that: require a fail safe valve closure in the event of a power loss. The uninterrupted supply works in conjunction with the actuator to control the valve position on loss of power. A relay control mounted inside of the actuator can be set to automatically close the valve or open the valve once power has been lost.
Most applications can be safely operated 2-4 times on battery backup. However, consult Valtorc for other cycle requirements, as a custom battery backup may be available for longer cycle operations.
