Designed to control the flow of both water and steam, the Powermite 656 Series Powermite Valves are available with normally open, normally closed, or three‑way mixing action. The Powermite 656 Series Valves are recommended for use with hot or chilled water and steam for control of convectors, fan coil units, radiation, reheat coils, and similar terminal unit applications. The dual sealing packed design is excellent for applications for higher‑pressure systems encountered in high rise buildings. The compact size is excellent for use when space is limited.
