Unlike intermittent duty starter solenoids

reducing mechanical strain on the venter motor and maintaining factory-spec performance across commercial installations

applying a thin layer of thermal conductive grease can further improve response time on uneven piping surfaces

meaning the switch opens on temperature rise

maintaining a reliable seal under rigorous thermal cycling

Siemens Building Technology 599-03170 Valve Refrigerant Unlike intermittent duty starter solenoidsThe Siemens Building Technology 599 03170 Valve is a rugged, 2 inch normally open globe valve designed for demanding hydronic and steam applications. As the direct replacement for the legacy DG2 2 40, this Flowrite 599 series valve body features a heavy duty bronze body and reliable brass trim, optimized for high performance flow control. With an equal percentage flow characteristic and a 40 Cv rating, it ensures precise modulation and stable loop
