Johnson Controls VG1845BNH943BGB 3/4" Three-Way NPT Ball Valve with Spring-Return Actuator 11.7 Cv 24V

The Johnson Controls VG1845BNH943BGB is a factory-assembled, 3/4-inch three-way ball valve from the VG1000 Series, paired with an M9220 spring-return electric actuator. Designed for commercial HVAC hydronic systems, this assembly provides precise on/off flow control for heating and cooling coil applications, diverting or mixing fluid between Port A (Coil) and Port B (Bypass) through the common Port AB.

Key Features:

• Valve Size: 3/4 in. (DN20) three-way ball valve
• End Connections: NPT threaded end connections
• Trim Material: Stainless steel trim for corrosion resistance
• Flow Coefficient: 11.7 Cv (Port A / Coil port)
• Actuator Type: M9220 Series spring-return electric actuator
• Control: 24 VAC, 2-position (on/off) control
• Spring Return Action: Port A (Coil) closed on loss of power — normally closed (NC)
• End Switches: Integrated end-of-travel switches included
• Static Pressure Rating: 580 psig
• Factory Assembled: Valve and actuator pre-assembled and tested — reduces field installation time

Part of Johnson Controls' industry-leading VG1000 Series, this assembly is engineered for long service life and leak-proof performance in unit ventilators, VAV boxes, fan coil units, and similar HVAC equipment. The spring-return design ensures the valve fails to a safe, normally closed position on Port A in the event of a power loss, providing reliable system protection.
