Belimo B220HT731+LF24-S Control Valve Cv with On/Off Actuator - 3/4 2-Way 7.31 24V

The Belimo B220HT731+LF24-S is a high-temperature characterized control valve (HTCCV) assembly designed for precise flow control in HVAC applications. This compact unit combines a 3/4-inch two-way brass valve body with an integrated LF24-S spring return actuator, providing reliable on/off control for heating and cooling systems.

Key Features:

• 3/4-inch NPT threaded connections for easy installation
• Two-way valve design with 7.31 Cv flow coefficient for optimal performance
• High-temperature rated valve body suitable for demanding applications
• 24VAC spring return actuator with fail-safe positioning
• On/Off control operation with reliable switching
• Characterized valve plug for linear flow characteristics
• Compact integrated design reduces installation time and labor
• Auxiliary switch (SW) included for status indication

This valve assembly is ideal for hydronic heating and cooling systems, chilled water applications, and hot water systems where reliable shutoff and flow control are critical. The spring return actuator ensures the valve returns to its fail-safe position during power loss, providing system protection and safety.
