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.

Figure 4. Close-off Pressures.

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.

In the event of power failure, a spring return

actuator returns the valve to its normal position with

the upper port closed and the bottom port open.

Non-spring return actuators will hold the last

commanded position. See the Technical

Instructions of the various actuators for additional

information.

Figure 5.

If this valve is used in diverting applications, the following conditions apply:

Diverting service with modulating control can use mechanical actuators such as the

SAX and SKB/D. The differential pressure must not exceed 90% of the maximum

differential pressure specified for the three-way valve in mixing service.

Diverting service with a pneumatic actuator can only be used with two-position control.

To change over from one port to another there must be no system pressure. The pump

is turned off.

Sizing 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.

Some variables that must be determined are:

•The medium to be controlled, such as water, etc.

•The maximum inlet temperature and pressure of the medium at the valve.

•The pressure differential that will exist across the valve under maximum load

demand.

•The maximum capacity the valve must deliver.

•The maximum line pressure differential the valve actuator must close against.

•See the Control Valve Selection and Sizing (AB-1) section of HVAC

Systems/Controls Reference Data (125-1853) for further recommendations.

See Table 2 and Table 3 for valve capacities.

Mounting and

Installation •Install the valve so that the flow follows the direction of the arrow indicated on the

valve body.

•For best performance, install the valve assembly with the actuator above the valve

body. The valve and actuator can be installed in any position between vertical and

horizontal. Siemens Building Technologies does not recommend installing the valve

assembly so that the actuator is below horizontal or upside down.

•Allow sufficient space for servicing the valve and actuator. See Table 8 for valve

body dimensions. See Figure 6 and Table 7 for dimensions of the service envelope

recommended around the actuator.

NOTE: Instructions for field mounting an actuator, wiring diagrams, and start-up are

covered in the Technical Instructions and Installation Instructions for each

actuator.
