Johnson Controls Globe Valve Assembly with Pneumatic Actuator and Positioner

Johnson Controls globe valve assemblies with pneumatic actuators and positioners are factory-assembled control valves. They regulate hot water, chilled water and steam flow in commercial and industrial HVAC and building automation systems. Each assembly combines a modulating globe valve body, a spring-and-diaphragm pneumatic actuator and a positioner. A pneumatic control signal from the building controller sets the valve stem position. These assemblies are also called pneumatic control valves, actuated globe valves or valve and actuator assemblies.

Key Features:

• Factory-assembled design: The valve body and pneumatic actuator arrive matched as one assembly, ready to install.
• Positioner for accurate control: The positioner uses stem feedback to hold the valve at the position the controller commands. It also compensates for flow surges in the piping and gives extra positioning power for sequenced operation.
• Durable construction: Johnson Controls globe valve lines such as the VG7000 Series use bronze bodies with brass or stainless steel trim. The actuators have corrosion-resistant housings.
• Spring-return operation: The actuator's spring returns the valve to its normal position when control air pressure is removed. Normally open and normally closed configurations are available.
• Flexible configurations: Two-way and three-way mixing styles are offered across the product line.
• Tight shutoff: Johnson Controls designs these valves for tight shutoff, which supports energy efficiency and occupant comfort.
• Visual position indication: Pneumatic actuators in the line include a stroke or position indicator so you can check valve position at a glance.

These assemblies suit HVAC applications that need stable, proportional control of water or steam. They work well for replacement and retrofit jobs and for new installations. Johnson Controls is a long-established name in building controls. Select the child item that matches your required body style, connection and actuator spring range.
