Return-temperature Control Valves

Gestra return-water temperature control valves mainly include the CW41, CW44, BW31, and BW31A product series. The CW41 and CW44 series use a cooling-water temperature-controlled flow-limiting design for temperature-limiting regulation in cooling-water systems. The BW31 and BW31A series use a return-water temperature control design for temperature regulation in return-water systems. When selecting a model, consider the specific drive and structural design, with particular attention to the specifications and technical documentation, including the Art. Nr., DN, and PN tables.
