Belimo Ball Valve Actuator Cv On/Off Spring Return

Belimo ball valve assemblies with an on/off spring return actuator pair a Belimo control valve body with a factory-fitted rotary actuator. They are used in HVAC and hydronic systems to open or close water flow. Also known as a spring return ball valve actuator, fail-safe on/off valve, or motorized ball valve, this line is built for building automation and commercial heating and cooling applications.

Key Features:

• Spring return fail-safe operation: if power is lost, the actuator drives the valve to its set safe position, either open or closed. This helps meet system sequence requirements.
• On/off control: the valve moves to the position set by a standard control signal from the building control system.
• Ball valve design: the design gives high close-off capability and tight shutoff, which helps limit energy loss and operating costs.
• Factory-fitted actuator: the valve and actuator arrive as a matched assembly, so there is no field pairing of components.
• Valve types: the line includes Belimo characterized control valves and standard ball valves.
• Auxiliary switch options: some models include an integrated SPDT auxiliary switch for position feedback.
• Voltage options: the line covers a range of actuator supply voltages for different control systems.

Belimo is a well-known manufacturer of actuators, valves, and sensors for HVAC. Each assembly is rated by its flow coefficient (Cv), so the valve can be matched to the flow needs of the system. Models differ in valve configuration and Cv, so choose the child item that suits your application.
