Belimo · Motors & Motion

Description  The Belimo B231+ARX24-SR-T N4 is a factory-assembled characterized control valve with an integrated non-spring return actuator for precise hydronic flow control. It combines a 2-way DN 1-1/4 inch valve body with stainless steel trim and a 24 V AC/DC modulating actuator for accurate proportional control.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category HVAC Control Components Part Number B231+ARX24-SR-T N4 Subcategory Characterized Control Valves Valve Type Characterized Control Valve (CCV) Valve Pattern 2-way Valve Size 1.25 in (DN 32) Cv Rating 25 Flow Characteristic Equal percentage End Connection Internal thread Trim Material Stainless steel Fluid Compatibility Chilled or hot water, up to 60% glycol Body Pressure Rating 400 psi Actuator Type Non-spring return, modulating Control Signal 2–10 VDC Actuator Voltage AC/DC 24 V Power Consumption (Running) 2.5 W Power Consumption (Holding) 0.4 W Power Consumption (Sizing) 5 VA Protection Rating IP66/67 Enclosure Rating NEMA 4X, UL Type 4X Electrical Connection Terminal strip Weight 1 lb   Information About B231+ARX24-SR-T N4 The B231+ARX24-SR-T N4 is a Belimo characterized control valve assembly designed for precise flow modulation in hydronic HVAC systems. The valve body features an equal percentage flow characteristic and stainless steel trim to support stable control across varying load conditions. Its non-fail-safe actuator provides proportional positioning using a 2–10 VDC control signal, making it suitable for applications requiring continuous modulation rather than spring-return safety action. The factory-mounted actuator and NEMA 4X enclosure allow the assembly to operate reliably in demanding mechanical room and outdoor-rated environments. Key Features Characterized valve design: Provides equal percentage flow control for stable and accurate modulation across the operating range. Integrated valve and actuator assembly: Supplied factory-fitted to ensure correct sizing, alignment, and performance. Non-spring return actuation: Supports precise modulating control where fail-safe positioning is not required. Stainless steel trim: Enhances durability and corrosion resistance in chilled and hot water applications. Wide fluid compatibility: Designed for water systems with glycol concentrations up to 60 percent. Modulating control signal: Accepts a standard 2–10 VDC input for seamless integration with building automation systems. Rugged enclosure rating: IP66/67 and NEMA 4X protection support operation in harsh or washdown-prone environments. The B231+ARX24-SR-T N4 delivers the reliability and precision required for accurate hydronic flow control in commercial HVAC and building automation systems.
