Siemens Building Technology 373-03206 Mixing Valve Assembly Cv NSR HVAC Control Valves & Actuators - 3-Way 2 40 24V

The Siemens Building Technology 373-03206 is a professional-grade 3-way mixing valve assembly from the Flowrite 599 Series, designed for precise hydronic control in commercial and residential HVAC applications. This complete valve and actuator assembly features a 2-inch line size with a flow coefficient (Cv) of 40, providing excellent flow capacity for medium to large zone control applications.

Key Features:

• Bronze body construction with brass trim for durability and corrosion resistance
• Female NPT threaded connections (FxF) for easy installation
• 24-volt non-spring return (NSR) floating actuator for reliable modulating control
• ANSI Class 250 pressure rating for high-pressure applications
• Equal percentage flow characteristic for precise temperature control
• ANSI Leakage Class IV rating (0.01% of Cv) for tight shutoff
• 100:1 rangeability for excellent control throughout the operating range

This valve assembly is ideal for hot or chilled water applications including zone control systems, radiant floor heating, fan coil units, cooling ceilings, and hydronic heating systems. The 24V floating actuator provides smooth, modulating control for precise temperature regulation. Operating temperature range: 41°F to 122°F (5°C to 50°C).
