Belimo Ball Valves are used for regulating or isolating flow in HVAC systems, including chilled water, hot water, and glycol solutions. They are ideal for both two-position (on/off) and modulating control applications.

Belimo Ball Valves are available in brass, bronze, stainless steel, and cast iron. Material selection depends on the application environment, media type, and required pressure/temperature ratings.

2-way ball valves control flow in a straight line and are typically used for isolation or basic on/off control. 3-way ball valves allow mixing or diverting flow between ports, commonly used in hydronic heating and cooling systems.

Yes. When combined with Belimo modulating actuators, ball valves can provide precise flow regulation based on control signals such as 0–10V or 4–20mA.

Belimo designs its ball valves and actuators to be fully compatible. However, it's important to select the correct torque, control type, and mounting configuration for your specific valve model.

Yes, Belimo offers actuators with spring-return (fail-safe) functionality that can close or open the valve automatically in the event of a power loss. This is particularly useful for safety-critical applications.

Belimo Ball Valves are operated via rotary motion using electric actuators. These actuators can be on/off, floating point, or modulating depending on your control system.

Most Belimo Ball Valves are rated up to 600 psi for water applications. Pressure ratings vary depending on the valve size, material, and end connections, so always check the datasheet.

Yes, with the proper actuator housing or weather protection, Belimo Ball Valves can be installed outdoors. IP-rated enclosures are available for actuators operating in wet or harsh environments.

They are widely used in HVAC systems for heating and cooling loops, fan coil units, AHUs, and energy metering applications. 3-way models are ideal for blending or diverting flow in more complex circuits.

Yes, Belimo offers pre-assembled valve and actuator packages for faster installation and guaranteed compatibility. Custom packages can also be created for specific project requirements.

Selection depends on your flow requirements, system pressure, media type, valve size, and control signal. Belimo’s online tools and product documentation make sizing and selection straightforward.
