Information About B248+AFRB24-SR
The B248+AFRB24-SR combines a characterized control valve with a direct-mounted spring-return electric actuator for heating and cooling applications. Its stainless steel ball and stem are designed for chilled or hot water service with glycol concentrations up to 60%. The actuator supports 2–10 VDC or 4–20 mA proportional control and provides a spring-return function with a return time of less than 20 seconds. The assembly uses 2-inch internally threaded connections and is rated for a maximum body pressure of 400 psi.
Key Features:
- Valve Pattern: 2-way characterized control valve for hydronic flow regulation.
- Flow Coefficient: Provides a 29 Cv rating for the 2-inch valve assembly.
- Stainless Steel Trim: Uses a stainless steel ball and stem for the valve trim.
- Spring Return: Provides automatic spring-return positioning when actuator power is removed.
- Proportional Control: Supports 2–10 VDC and 4–20 mA control signals for modulating operation.
- Actuator Torque: Produces 180 in-lb of torque for valve positioning.
- Power Supply: Operates from AC/DC 24 V power.
- Fluid Compatibility: Suitable for chilled or hot water systems containing up to 60% glycol.
The B248+AFRB24-SR delivers the reliability and precision required for proportional hydronic flow control in HVAC heating and cooling systems.
