Schneider Electric Pneumatic Globe Valve Assembly Normally Open

The Schneider Electric (Barber Colman) Pneumatic Globe Valve Assembly is a factory-assembled globe valve and pneumatic actuator package. It is built for flow control of hot water, chilled water, and low-pressure steam in commercial HVAC systems. Because it comes pre-assembled, the valve and actuator are matched and ready to install. It is also known as a pneumatic control valve or actuated globe valve.

Key Features:

• Normally open, spring-return operation: the valve returns to its open, fail-safe position when the air signal is lost.
• Pneumatic actuator: a spring-return diaphragm actuator supports two-position (on/off) or proportional control from a compressed air signal.
• Globe valve design: a 2-way body with linear stem movement and a stem-up-open action gives smooth, repeatable modulation.
• Durable construction: bronze valve body with brass trim.
• Modified equal percentage flow characteristic: gives fine control across a wide range of flow rates in hydronic heating and cooling applications.
• Broad media compatibility: hot or chilled water, low-pressure steam, and glycol solutions.
• Pre-assembled: the valve body, linkage, and actuator are mounted together at the factory.

The assembly suits coil control, heating and cooling loops, and other pneumatic building control systems. It also suits replacement of existing Barber Colman and Schneider Electric pneumatic valves. Pipe size and Cv rating differ by model number, so choose the specific model that matches your piping and flow requirements.
