These two-way and three-way balanced hydronic valves are designed for on-off control or floating control of hot and/or chilled water. Applications include central heating and/or cooling systems, fan coil systems, radiators and convectors. The three-way valves are suitable for installation in a diverting and/or mixing mode. Order models with conformal coated printed circuit boards for chilled water applications.

Depending on the model selected, they can be controlled by either a low or line voltage SPST or SPDT or floating (center-off) controller such as a room thermostat, aquastat, or flow switch.
