The valve features a precision-machined ball with equal percentage characteristics and stainless steel trim to ensure durability and consistent performance under varying load conditions. Its factory-mounted spring return actuator operates on AC/DC 24 V and supports modulating control with selectable direction of rotation and integrated position feedback. Built for maintenance-free service, the assembly combines tight shutoff, reliable fail-safe operation, and compatibility with modern building automation systems. Key Features Characterized Ball Valve Design: Precision-engineered ball and seat provide true equal percentage flow control for accurate modulation. Integrated Spring Return Actuator: Automatically drives the valve to a predefined fail-safe position upon power loss for system protection. Modulating Control Capability: Supports 2…10 VDC control signals with optional 4…20 mA input using an external resistor. High Pressure and Tight Shutoff Performance: Rated for 400 psi body pressure with 200 psi close-off and zero leakage for A–AB. Wide Fluid and Temperature Compatibility: Designed for chilled and hot water systems with glycol concentrations up to 60%. Pre-Wired Electrical Connection: Supplied with 18 GA appliance cable and 1/2" NPT conduit connector for simplified installation. Durable Actuator Protection: IP54 and NEMA 2 ratings protect internal components in typical HVAC mechanical environments. The B232+AFRB24-SR delivers the reliability and precision required for accurate hydronic flow modulation and fail-safe control in commercial HVAC systems.
