Description
Johnson Controls V48AC-2 Three-Way Pressure Actuated Water Regulating Valve
The Johnson Controls V48AC-2 is a precision-engineered, three-way pressure actuated water regulating valve designed for reliable condenser water flow control in commercial HVAC and refrigeration systems. Built with a durable cast brass body and a 3/4″ NPT connection, this valve automatically modulates water flow in response to system refrigerant pressure, helping maintain optimal condensing conditions and protect equipment from high-pressure faults.
Key Features
- 3/4″ NPT inlet/outlet connection for easy integration into existing piping systems
- Three-way valve configuration for precise condenser water flow management
- Normally closed side opening point range of 145 to 190 PSI for accurate pressure-responsive control
- Cast brass body construction for long-lasting durability and corrosion resistance
- Style 45 pressure element for reliable, repeatable actuation
- 30″ capillary tube with 1/4″ flare nut for flexible remote sensing installation
- Pressure actuated operation — no external power source required

Application
The V48AC-2 is ideal for use in air-cooled and water-cooled refrigeration and HVAC systems where condenser water flow must be regulated based on refrigerant head pressure. The valve opens on a rise in refrigerant pressure, directing water through the condenser to maintain safe operating conditions. The 30″ capillary with 1/4″ flare nut allows the pressure element to be conveniently located at the refrigerant sensing point, providing installation flexibility in tight mechanical rooms.
