Belimo · Motors & Motion

Description  The Belimo B280+ARB24-3 is a 3-inch, 2-way characterized control valve assembly designed for accurate flow control in hydronic HVAC systems. It combines a high-capacity brass ball valve with a non spring return floating point actuator operating on AC/DC 24 V.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category Control Valves Part Number B280+ARB24-3 Subcategory Characterized Control Valves Valve Type Characterized Control Valve (CCV) Valve Size 3 in (DN 80) Flow Pattern 2-way Cv Rating 170 Flow Characteristic Equal percentage Body Pressure Rating 400 psi Close-Off Pressure 100 psi Leakage Rate 0% for A–AB Pipe Connection Female NPT Controllable Flow Range 75° Fluid Compatibility Chilled or hot water, up to 60% glycol Fluid Temperature Range 0…212°F (-18…100°C) Valve Body Material Nickel-plated brass Ball Material Stainless steel Seat Material PTFE Stem Material Stainless steel Actuator Type Non spring return Control Mode On/Off, Floating point Nominal Voltage AC/DC 24 V Power Consumption (Running) 2.5 W Power Consumption (Rest) 0.5 W Running Time 90 s / 90° Degree of Protection IP54 / NEMA 2 Weight 11.2 lb   Information About B280+ARB24-3 The B280+ARB24-3 is part of Belimo’s characterized control valve range developed to provide stable and repeatable flow control in medium to large hydronic circuits. The valve uses a full-flow stainless steel ball and equal percentage control characteristic to maintain consistent regulation across varying load conditions. Its factory-mounted ARB24-3 actuator supports floating point control and non fail-safe operation, ensuring reliable positioning during normal system operation. Built for maintenance-free service, this assembly integrates durable materials with precise actuator control for long-term HVAC performance. Key Features High Capacity Two Way Valve Design: Cv 170 rating supports effective control of large water volumes in distribution piping. Equal Percentage Flow Characteristic: Provides smooth and predictable modulation across the valve’s operating range. Non Spring Return Floating Actuator: Supports floating point and on/off control while maintaining last position on power loss. Compact Brass Valve Construction: Nickel-plated brass body with stainless steel trim ensures corrosion resistance and durability. Low Power Consumption: Efficient 24 V actuator design minimizes electrical load on control transformers. Service-Friendly Operation: Manual override and mechanical position indication simplify commissioning and maintenance tasks. Proven HVAC Compatibility: Rated for chilled and hot water systems with glycol mixtures up to 60%. The B280+ARB24-3 delivers the reliability and precision required for accurate hydronic flow control in commercial HVAC applications.
