Belimo NPT Control Valve with Spring Return Actuator

The Belimo NPT control valve with spring return actuator line is a factory-assembled hydronic valve and actuator package. It is used to control chilled water and hot water flow in HVAC systems. These valves are also called characterized control valves (CCV) or zone valves. They suit air handling unit coils, fan coil unit coils, and other terminal heating and cooling equipment.

Key Features:

• Spring return fail-safe actuator: The actuator drives the valve to its default position when power is lost. This protects coils and equipment.
• Threaded NPT end connections: They allow straightforward installation in standard threaded piping.
• Characterized ball valve design: It combines the tight close-off of a ball valve with a flow characteristic suited to modulating control. Belimo describes this as high rangeability, with the valve self-cleaning to resist debris buildup.
• Durable construction: Valve bodies are typically forged brass. Internal parts such as the ball and stem are typically stainless steel.
• Suitable media: The valves are used with chilled water, hot water, and water-glycol mixtures.
• Normally open or normally closed operation: Operation depends on how the actuator is mounted to the valve.

Belimo is a well-known manufacturer of HVAC actuators, valves, and sensors. Each valve and actuator pairing is matched for reliable operation, so you do not need to size and assemble separate components. Choose the specific variant that fits your system's piping and control requirements.
