Series 19 Smart SAV Modulating Failsafe Electric Actuator – Butterfly Valve Packages

The Series 19 modulating failsafe combines the features of a modulating unit with the reliability of a failsafe unit. With all of the same features of the modulating unit, the modulating failsafe employs a capacitor discharge design for the failsafe ability. When the power supply is lost, the failsafe system will cycle the valve to a predetermined position (open, closed, or as is).

Series 19 SAV Smart Pack® electric actuators can be factory-mounted on Type-57P, Type-57IL, Type-57LIS, Type-55, Type-55IS and Pool-Pro® butterfly valves. Choose from PVC, CPVC, PP, and PVDF valve bodies, and socket or threaded end connectors (ball valves). One part number for valve and actuator packages makes ordering easy. All actuated Smart Packs® are available in the four different models: on/off, modulating, failsafe, and modulating failsafe.
