Operating on 24 VAC/DC power, it provides accurate flow regulation with high Cv capacity for larger piping applications.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category Control Valves Part Number B224VS+NMB24-3-X1 Subcategory Ball Valves Valve Type Ball Valve (VS) Valve Size 1 in (DN 25) Flow Pattern 2-way Flow Coefficient Cv 43 Flow Characteristic Modified equal percentage Controllable Flow Range 90° rotation Leakage Rate ANSI Class VI Body Pressure Rating 600 psig WOG Close-Off Pressure 600 psi Max Differential Pressure (Steam) 35 psi Fluid Compatibility Chilled water, hot water, up to 60% glycol, steam Fluid Temperature Range (Water) -22…280°F (-30…138°C) Pipe Connection NPT female Valve Body Material Bronze B584-C84400 Ball Material 316 Stainless Steel Stem Material 316 Stainless Steel Seat Material RPTFE Actuator Type Non spring return Control Type Floating point Nominal Voltage AC/DC 24 V Power Consumption (Operation) 2 W Power Consumption (Rest) 0.2 W Transformer Sizing 4 VA Angle of Rotation Max. 95°, adjustable Running Time 95 s / 90° Protection Rating IP54, NEMA 2 Weight 3.7 lb   Information About B224VS+NMB24-3-X1 The B224VS+NMB24-3-X1 is part of Belimo’s VS series ball valve assemblies engineered for high-capacity flow control in commercial HVAC systems. The bronze valve body combined with stainless steel internal components provides durability, corrosion resistance, and stable performance under high pressure conditions. Factory-fitted with the NMB24 non-fail-safe actuator, the assembly supports floating point control for accurate open/close positioning without spring return action. This configuration is commonly used in hydronic heating and cooling circuits where proportional positioning and tight shutoff are required. Key Features High Cv 43 Flow Capacity: Supports efficient flow control in 1-inch piping systems while maintaining predictable pressure drop characteristics. Integrated Valve and Actuator Assembly: Factory-mounted configuration ensures proper alignment, reduced installation time, and consistent operational performance. Non Spring Return Actuation: Designed for applications where continuous powered positioning is preferred over fail-safe spring return operation. Floating Point Control Logic: Enables precise incremental positioning using open/close control signals from building automation systems. ANSI Class VI Tight Shutoff: Provides minimal leakage to support accurate isolation and improved energy efficiency. Durable Valve Construction: Bronze body with stainless steel ball and stem, combined with PTFE-based seals, supports long service life. Manual Override Capability: External push button allows manual positioning during commissioning or maintenance activities. The B224VS+NMB24-3-X1 delivers the reliability and precision required for controlled hydronic flow regulation in commercial HVAC heating and cooling applications.
