Description
The Johnson Controls V46AC-26 is a commercial-grade, direct acting, pressure actuated water regulating valve engineered for reliable refrigerant system water flow control. Built with a cast brass body and rated for a 70 to 260 PSI opening point range, this valve is designed for use with non-corrosive refrigerants in demanding HVAC and refrigeration applications.
Product Overview
The V46AC-26 operates on a direct acting principle, opening in response to refrigerant pressure to modulate condenser water flow and maintain efficient system operation. The standard flow, commercial-type design makes it well-suited for a wide range of light commercial and commercial cooling systems. The valve features a 1/4″ external flare fitting (Style 5) pressure element connection, ensuring a secure and leak-free interface with the refrigerant circuit.
Key Features
- 3/4″ NPT water connection for straightforward installation into standard piping
- 70 to 260 PSI opening point range for broad refrigerant system compatibility
- Direct acting, pressure actuated operation — no external power required
- Cast brass body construction for durability and corrosion resistance
- Standard flow, commercial type design for light commercial and commercial HVAC applications
- Compatible with non-corrosive refrigerants
- 1/4″ external flare fitting (Style 5) pressure element for secure refrigerant connection
Application
The V46AC-26 is ideal for water-cooled condensers in commercial refrigeration and air conditioning systems. As refrigerant head pressure rises, the valve opens to allow condenser water flow, protecting the system from high-pressure conditions and improving overall efficiency. Its robust cast brass construction ensures long service life in commercial environments.
