Belimo 3/4" Sweat 3-Way Zone Valve

The Belimo 3-way sweat zone valve is a motorized zone control valve for hydronic heating and cooling systems. It diverts or mixes flow through a coil or terminal unit and is made for commercial HVAC jobs. It has soldered (sweat) pipe connections and a spring-return actuator, so it can be used as a hydronic zone valve or 3-way diverting valve.

Key Features:

• 3-way flow pattern for diverting or bypass control of chilled or hot water zones
• Sweat (solder) end connections for a permanent, leak-resistant joint in copper piping
• Normally closed, spring-return actuator that returns the valve to its default position when power is removed
• Auxiliary switch that can signal valve position or interlock other equipment
• Cv-rated to support flow and capacity matching for the zone
• Available with different actuator voltage options, so it can be matched to the control transformer or line voltage on site
• Built by Belimo, a well-known maker of actuators and control valves for HVAC

Typical applications include fan coil units, unit ventilators, reheat coils, fin tube and radiant panels. Belimo's related ZoneTight zone valve line is described by the manufacturer as compact and easy to install, with low power consumption and tight shut-off. Choose the variant that matches your actuator voltage and flow requirements.
