Three-Way Valves

2-1/2 to 6-inch Flanged Iron Body

Description The Flowrite VF 599 series three-way valves are designed to work with either a

pneumatic or electronic actuator. They are available in both ANSI Class 125 and 250.

Features •Valve flange face-to-face dimensions meet ISA 75.03 standards

•Direct coupled universal bonnet

•Choice of bronze or stainless steel trim

•ANSI Leakage Class IV (0.01% of Cv)

•Cartridge type packing

•Optional service flange available

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.

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 155-304P25 (TB 249)

for selection procedure and ordering codes.

Valve assemblies can be ordered using the numbers in Table 1.

The service flange is ordered separately.

Operation

This Flowrite three-way valve is designed as a mixing

valve.

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. Non-spring

return actuators will hold the last commanded

position. See the Technical Instructions of the

various actuators for additional information.

If this valve is used in diverting applications, the

following conditions apply:

Diverting service with modulating control can only

use the electro-hydraulic actuator, SKB/C. 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 may 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 which must be determined are:

•The medium to be controlled: 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 AB-1 Control Valve Selection and Sizing (Document Number 155-285) for

further recommendations.

See Tables 6 and 7 for valve capacities.

Mounting and

Installation

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

valve body identification tag.

•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 below horizontal or upside down.

•If installing a service flange, see Table 13 for proper placement.

•For flange dimensions and bolt hole information, see 155-303P25 (TB 248).Allow

sufficient space for servicing the valve and actuator. See Table 12 for valve body

dimensions. See Figure 5 and Table 11 for dimensions of the service envelope

recommended around the actuator.

•A lower seat tool is required for removing a three-way valve. See Table 10 for part

numbers.

NOTE: Instructions for field mounting an actuator, spring adjustments, wiring diagrams,

and start-up are covered in the Technical Instructions and Installation

Instructions for each actuator.
