Siemens Building Technology 373-03202 Mixing Valve Assembly with Electronic Actuator HVAC Control Valves & Actuators - 3-Way

The Siemens Building Technology 373-03202 is a complete valve assembly designed for precise control in hydronic heating and cooling systems. This assembly combines a high-quality 3-way mixing valve with an integrated SAX81.03U electronic actuator for reliable, automated flow control.

Valve Specifications:

• 3-way mixing configuration for blending or diverting flow
• 3/4-inch female x female (FxF) threaded connections
• 6.3 Cv flow coefficient for optimal capacity
• Equal percentage/linear flow characteristic
• Brass trim construction for corrosion resistance and durability

Actuator Features:

• SAX81.03U electronic actuator with 24 VAC power supply
• Floating control for 3-position operation
• Non-spring return (fail-in-place) design
• 180 lb-in (800N) nominal force output
• 30-second run time for full stroke
• 3/4-inch stroke length for complete valve modulation
• Direct-coupled installation requires no special tools
• Manual override with visual position indication
• UL listed for plenum installations

This valve assembly is ideal for applications requiring automated temperature control, including fan coil units, unit heaters, radiant heating systems, and chilled water distribution. The floating control design provides energy-efficient operation by positioning the valve only when adjustment is needed.
