Siemens 267-03204 3-Way Mixing Valve 1-1/4" FxF 24V Actuator

The Siemens Building Technology 267-03204 is a 3-way mixing valve designed for commercial HVAC hydronic systems. This valve features female NPT threaded connections on both ends (FxF) with a 1-1/4 inch port size, making it suitable for medium-flow applications in heating and cooling systems.

Key Features:

• 3-way mixing valve configuration for blending hot and cold water streams
• 1-1/4 inch female NPT threaded connections (FxF)
• 24V AC/DC actuator with non-spring return (NSR) operation
• 16.0 Cv flow coefficient for optimal flow control
• Brass or bronze construction for durability and corrosion resistance
• Designed for commercial building automation and HVAC control systems

This mixing valve is ideal for applications requiring precise temperature control in hydronic heating and cooling systems, including boiler systems, chilled water systems, and radiant heating installations. The non-spring return actuator maintains valve position during power loss, providing reliable control in critical HVAC applications.
