Siemens Building Technology Mixing Valve Assembly Pneumatic Actuator HVAC Control Valves & Actuators

The Siemens Building Technology mixing valve assembly with pneumatic actuator is a factory-assembled 3-way mixing control valve. It pairs a globe-style valve body with an air-operated actuator, so you can regulate water flow in commercial and industrial HVAC systems. It is also known as a pneumatic valve actuator assembly or 3-way mix valve.

Key Features:

• 3-way mixing design: Blends two incoming flow streams into one outlet stream for accurate temperature control.
• Pneumatic actuation: A spring-return pneumatic actuator positions the valve in response to the control air signal. Some assemblies include a factory-mounted positioner for more precise modulation.
• Durable construction: Bronze or brass valve bodies with brass or stainless steel trim resist corrosion and wear.
• Female NPT end connections: These allow straightforward installation into threaded piping.
• ANSI Class 250 rating: The valve bodies are built for dependable operation in hot water, chilled water and glycol-solution applications.
• Factory-matched components: The valve and actuator are supplied as an assembly, so you don't need to match parts yourself.

These assemblies suit hydronic heating and cooling loops, air handler coil control, and other building automation applications that need reliable mixing or temperature blending. Siemens Building Technology is a long-established name in building controls, and its valve and actuator assemblies are used in commercial HVAC installations.
