A zone valve is used to control the water flow to a particular zone and can be used in applications such as hydronic heating (baseboard, radiant), geothermal, fan coils and others. Browse our selection of zone valves from leading industry manufacturers such as Taco and Honeywell.
Zone valves serve the purpose of controlling the supply of water to hydronic, radiant or geothermal zones to maintain desired temperatures. In a typical residential heating application, where boiler or other heat source produces hot water, installing zone valves will allow for independent temperature control in each room or floor via the thermostat. Zone valves are typically installed in combination with a zone valve control, which serves as an intermediary between the boiler, circulator pump, zone valves and thermostat(s) and allows for simplified wiring without installation of additional controls.
Each zone valve consists of a valve body and an actuator. This design allows to replace actuator or actuator motor if it stops functioning without replacing the entire valve.
Zone valves are either normally closed (NC) or normally open (NO) with former being the most common. The NC valves are closed by default (when power is off) and only open when power is supplied. The opposite applies to the NO valves.
Zone Valves by Taco
Taco manufactures a wide array of products for heating and cooling zone control with application-specific zone valves designed to meet the individual project needs. Taco zone control valve series include the gear-driven, energy-efficient Sentry series and heat-motor type, heavy-duty classic 570, 560, 550 and geothermal series for hydronic, radiant, geothermal heating and cooling applications.
Zone Valves by Honeywell
Honeywell brand zone valves sold at PexUniverse include 2-way V8043 and V8044 series, as well as 3-way V4043 series valves in sizes 1/2" through 1" with terminal connections or wire leads. Honeywell zone valves are among the most popular in the industry and can be used for applications such as baseboard or radiator heating, radiant floor heat, chilled water cooling and others. Removable actuator head makes servicing the valve easy and does not require shutting off the water supply.
