Johnson Controls Three-Way Mixing Globe Valve with Pneumatic Actuator and Positioner

The Johnson Controls three-way mixing globe valve with pneumatic actuator and positioner is a factory-assembled HVAC control valve (also called a mixing valve or modulating control valve). It regulates the flow of hot water, chilled water or steam in building heating and cooling systems in response to a pneumatic signal from a controller.

Key Features:

• Three-way mixing configuration: blends or diverts flow between ports. The globe design gives a linear response in three-way service.
• Pneumatic actuator: positions the valve in response to a controller's pneumatic signal. Spring-return models provide fail-safe operation.
• Positioner: a pneumatic or electro-pneumatic positioner supports accurate, proportional modulation.
• Durable construction: the line includes bronze or cast iron valve bodies with brass or stainless steel trim, depending on series.
• Tight shutoff: designed to support occupant comfort and energy efficiency.
• Flexible actuation: Johnson Controls globe valve series are designed to accept a range of electric and pneumatic actuators. This allows field retrofits.

Johnson Controls is a long-established name in building automation and HVAC controls. These valve assemblies suit commercial HVAC applications such as air handlers, coils, and heating and chilled-water loops. Choose the specific connection type, flow coefficient and actuator spring range that match your system requirements.
