Description
The Johnson Controls V48AD-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 iron body and a 1″ NPT connection, this valve responds directly to refrigerant head pressure to modulate condenser water flow — eliminating the need for separate controls and improving system efficiency.
Key Features
- Three-way valve design for flexible bypass or diverting water flow configurations
- 1″ NPT inlet/outlet connections for straightforward installation into standard piping systems
- Normally Closed (NC) side opening point range of 145 to 190 PSI for precise pressure-actuated control
- Cast iron body construction for long-lasting durability in demanding commercial environments
- 30″ capillary tube with 1/4″ flare nut (Style 45) pressure element for accurate refrigerant pressure sensing
- Pressure actuated operation — no external power source required

Application
The V48AD-2 is ideal for use in commercial air conditioning and refrigeration systems where condenser water flow must be regulated in response to system head pressure. The three-way configuration allows the valve to simultaneously control flow to the condenser while bypassing excess water, maintaining optimal system pressures across varying load conditions. The Style 45 pressure element with 30″ capillary provides flexible installation positioning relative to the refrigerant line being sensed.
