Description
The Siemens Building Technology 268-03203 is a fully assembled 3-way mixing valve engineered for reliable hydronic flow control in commercial and industrial HVAC systems. Combining a durable bronze valve body with brass trim and a factory-mounted pneumatic actuator, this assembly arrives ready for installation — reducing labor time and ensuring proper component compatibility right out of the box.
Valve Assembly Overview
This mixing valve assembly is designed to blend or divert fluid streams in heating and cooling hydronic circuits. The 3-way mixing configuration allows precise control of supply water temperature by proportioning flow between two inlet ports and one common outlet, making it ideal for air handling units, fan coil systems, and zone control applications.
Key Features
- 3-way mixing valve configuration for hydronic heating and cooling systems
- 1″ NPT end connections for straightforward pipe integration
- 10 Cv flow coefficient for accurate flow capacity sizing
- Bronze valve body for excellent corrosion resistance and durability
- Brass trim components for long-lasting, reliable sealing performance
- Factory-mounted pneumatic actuator — no field assembly required
- 3–8 PSI spring range actuator for direct compatibility with standard pneumatic control systems
- Siemens Building Technology quality construction and engineering
Pneumatic Actuator Details
The integrated pneumatic actuator operates on a 3–8 PSI spring range, making it compatible with conventional pneumatic control signals used throughout commercial building automation systems. The actuator provides smooth, proportional valve positioning in response to control air pressure, ensuring stable and accurate temperature regulation.
