Belimo B330+ARX24-SR-T 1.25" 3-Way Control Valve with Actuator 19 Cv 24V 2-10V NEMA 4H

The Belimo B330+ARX24-SR-T is a complete control valve assembly combining a 1.25-inch three-way brass ball valve (B330) with an ARX24-SR-T non-spring return actuator. This compact valve package is designed for hydronic HVAC systems requiring precise mixing or diverting control of chilled water, hot water, or glycol solutions.

Valve Specifications:

• Connection size: 1.25 inches (DN32) threaded
• Valve type: 3-way characterized control valve
• Flow coefficient (Cv): 19
• Body material: Dezincification-resistant brass (DZR)
• Pressure rating: PN25 (363 psi)
• Temperature range: -4°F to 266°F (-20°C to 130°C)

Actuator Features:

• Power supply: 24V AC/DC universal voltage
• Control signal: 2-10V DC modulating
• Action: Non-spring return (maintains position on power loss)
• Running time: 150 seconds for 90° rotation
• Torque: 35 in-lbs (4 Nm)
• Enclosure: NEMA 4/4X (IP54) weatherproof housing
• Feedback: Auxiliary position feedback switch included

The non-spring return design holds the valve in its last position during power interruptions, making it ideal for applications where maintaining flow configuration is critical for system protection. The actuator features manual override capability and auxiliary position indication for commissioning and diagnostics.

This assembly is factory-mounted and leak tested, ensuring reliable installation and immediate operation. Suitable for commercial building automation systems, district heating/cooling, and process temperature control applications.
