Information About B232+AFRB24
The B232+AFRB24 is a Belimo characterized control valve assembly engineered for dependable on/off flow control in hydronic heating and cooling systems. The valve body uses an equal percentage characteristic to maintain stable control performance while accommodating higher flow capacity than standard ball valves. Its stainless steel trim and high pressure rating support long-term operation in demanding HVAC environments with varying load conditions. The factory-fitted spring return actuator ensures automatic movement to a safe position during power interruptions, supporting system protection and operational continuity.
Key Features
- Characterized valve geometry: Equal percentage flow characteristic supports stable and predictable control across the operating range.
- High-flow capacity design: Cv 37 rating enables efficient control of larger flow volumes in 1-1/4 inch piping systems.
- Fail-safe spring return actuator: Automatically drives the valve to a defined safety position upon loss of power.
- On/off control operation: Designed for applications requiring reliable open/close valve positioning rather than proportional modulation.
- Stainless steel trim construction: Enhances resistance to corrosion and wear in hot and chilled water systems.
- High pressure capability: Rated for 400 psi body pressure with 200 psi close-off for demanding system conditions.
- Integrated manual override: Allows manual valve positioning during commissioning or maintenance using the supplied hex crank.
The B232+AFRB24 delivers the reliability and precision required for secure shutoff control and dependable flow management in commercial HVAC and building automation systems.
