Three-Way Valves

1/2 to 2-inch Bronze Body

Siemens Industry, Inc.

Description

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.

Features

• ANSI Leakage Class IV (0.01% of Cv)

• Cartridge type packing

• Choice of brass or stainless steel trim

• Direct-coupled universal bonnet

Application

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.

Product Numbers

See Table 1.

Ordering a Valve

Plus Actuator

Assembly

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.

Operation As the valve stem moves downward, the flow through the NO port decreases and the flow through the NC port increases. As the valve stem moves upward, the flow through the NO port increases and the flow through the NC port decreases.

Technical Instructions Document Number 155-185P25 June 10, 2019 Sizing Flowrite 599 Series Three-Way Valves The sizing of a valve is important for correct system operation. An undersized valve will not have sufficient capacity at maximum load. An oversized valve can initiate cycling, and the seat and throttling plug can be damaged because of the restricted opening. Correct sizing of the control valve for actual expected conditions is considered essential for good control.
