The Flowrite VF 599 Series ANSI Class 250 three-way valves are designed to work with either a pneumatic or electronic actuator with a 3/4-inch (20 mm) stroke.
A typical application for the Flowrite three-way valve is the mixing of two different temperatures of water supplies.
The valve can also be used for throttling or bypass coil control applications. A pump is recommended on the coil circuit to improve the heat transfer characteristics of the coil and for freeze protection.
