Siemens Building Technology Mixing Valve with Actuator HVAC Control Valves & Actuators

Siemens Building Technology mixing valves with actuators are factory-assembled HVAC control valve assemblies. They blend two flow streams into one outlet stream for accurate temperature control in hydronic heating and cooling systems. Each assembly pairs a globe-style 3-way mixing valve body with a Siemens actuator, so it works as a complete control valve and actuator package.

Key Features:

• 3-way mixing design: combines two inlet flows into a single outlet to control temperature and match system loads.
• Valve and actuator assembly: the valve body and actuator come together as one unit. Depending on the model, the actuator is pneumatic or electronic.
• Durable construction: bronze or brass bodies, with trim options that vary by model.
• Precise flow control: equal percentage or modified equal percentage flow characteristics, with a range of Cv values across the line.
• Low leakage: Powermite-style globe valves are rated to ANSI Class IV leakage.
• Fail-safe options: spring-return and non-spring-return actuators are available, depending on the model.
• Optional positioner: some models come with a factory-mounted positioner for accurate, repeatable valve positioning.

These assemblies suit hot or chilled water control for terminal units such as fan coil units, convectors, radiation and reheat coils, and for larger air handling and hydronic loops. Siemens Building Technology is a long-established maker of building automation and HVAC controls, and these valves help maintain efficient, comfortable indoor climates.
