VG1841AD
The Johnson Controls VG1841AD is a 3-way ball valve, which can be used to regulate flow of water in systems that involve hydronics and heating as well as cooling systems. There are three types of operating mechanisms in this miniature valve, drain valve with a rotating ball type handling three ports for use in applications that require the ability to section off or change the flow of water. Constructed of brass for lasting and corrosion resistant, can withstand 200 psi close-off pressure and operating temperature of 23°F to 203°F, ideal for most residential and commercial HVAC applications. Although the valve is manually operated, it is used in conjunction with a 24VAC non-spring return electric actuator for automatic operation. Due to its small 1/2” pipe size, the valve is well suited to regulating water flow in localized areas of a heating or cooling system, which leads to better temperature regulation and lower energy consumption.
