Belimo B325+LF24-SR Ball Valve with Spring Return Proportional Actuator - 1 3-Way 24V

The Belimo B325+LF24-SR is a complete valve and actuator assembly featuring a 1-inch brass 3-way ball valve paired with an LF24-SR spring return proportional actuator. This assembly is designed for HVAC mixing and diverting applications requiring reliable modulating control of water or glycol solutions.

Key Features:

• 1-inch NPT threaded brass ball valve with 3-way configuration for mixing or diverting service
• 24 VAC/DC spring return actuator with proportional control (0-10 VDC or 2-10 VDC input signal)
• Fail-safe spring return functionality automatically returns valve to default position on power loss
• Floating bronze ball with PTFE seats for reliable shutoff and long service life
• Direct mount actuator coupling eliminates external linkages for simplified installation
• Operating pressure range suitable for standard hydronic systems
• Compact design minimizes space requirements in mechanical rooms and equipment

This pre-assembled valve and actuator combination provides plug-and-play installation for HVAC contractors and building automation professionals. The proportional control allows precise modulation for heating, cooling, and mixing applications in commercial and industrial building systems.
