Johnson Controls VG1845ER+938BGC 1-1/2" Three-Way Ball Valve with Spring-Return Actuator

The Johnson Controls VG1845ER+938BGC is a factory-assembled valve and actuator combination designed to regulate the flow of hot or chilled water in HVAC systems. This assembly combines a VG1845ER three-way forged brass ball valve with stainless steel trim and a VA9208-BGC-3 spring-return electric actuator with two auxiliary switches for precise control and position indication.

Valve Specifications:

• 1-1/2 inch NPT threaded end connections
• Three-way configuration for mixing or diverting applications
• Flow coefficient (Cv) of 29.2
• Forged brass body with 580 psig static pressure rating
• Stainless steel ball and blowout-proof stem for corrosion resistance
• Fluid temperature range of 23°F to 203°F (-5°C to 95°C)
• Graphite-reinforced PTFE seats for enhanced wear resistance
• 500:1 rangeability for accurate control under all load conditions

Actuator Specifications:

• VA9208-BGC-3 spring-return direct-coupled actuator
• 70 lb-in (8 N·m) running torque
• 24 VAC operation for on/off or two-position control
• Spring return to open position upon power loss
• Two SPDT auxiliary switches for end-stop indication
• 48-inch appliance cable with integral 3/8-inch FMC connector

This valve assembly is ideal for controlling chilled water, hot water, and 50% glycol solutions in commercial HVAC applications. The maintenance-free design performs reliably for over 200,000 full stroke cycles, even in iron-oxide contaminated water. The characterized insert provides equal percentage flow control for precise modulation.
