Assembly
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.
ANSI Leakage Class IV (0.01% of Cv)
Cartridge type packing
Choice of brass or stainless steel trim
Direct-coupled universal bonnet
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.
See Table 1.
To order a complete valve plus actuator assembly from the factory, combine the
actuator prefix code with the suffix of the valve assembly product number. See Flowrite
Technical Bulletins 155-772 and 155-776 for complete selection procedure and ordering
codes.
Valve assemblies can be ordered using the valve part numbers in Table 1 and the
actuator prefix codes in Table 7.
