2-1/2 to 6-Inch Valve, Two-Way & Three-Way,

and Actuator Assembly Selection

Siemens Industry, Inc.

Description

This Technical Bulletin will aid in the selection of a Flowrite 599 Series 2-1/2 inch to 6-

inch valve and actuator assembly. Begin with the graph of water capacity and the chart

of close-off pressures to select a valve and actuator according to specifications. Use

Tables 1 through 4 to identify product numbers.

These tables show all the possible combinations of the Flowrite 599 Series valves and

compatible actuators that can be ordered as complete valve assemblies from the

factory.

The dimensions of all valves and the service envelope required for each actuator are

included in Tables 5 through 7.

How to Use the

Selection Graphs

Use Figure 1, the water capacity graph, to select a valve. Locate the specified flow rate

on the vertical axis. Follow across on the horizontal line to the point of intersection with

the specified pressure drop. Choose the valve size from the heavy diagonal lines

across the graph.

Use Figure 2, the close-off pressure graph, to select an actuator. First locate the valve

action and actuator power source specified. Locate the bar that represents the valve

line size. The top of the bar indicates the maximum close-off pressure for tight close-

off.

Use the legend at the bottom of the graph to identify the actuator.

How To Use The

Valve Tables

Tables have been organized to help select a valve and actuator combination using

additional specifications.

Moving from left to right, identify the valve by selecting the combination of parameters

needed. Continue to the right to match the selected valve to a desired actuator.

A valve and actuator assembly part number is determined by combining the actuator

prefix code with the suffix of the valve product number.

NOTES:

1. No valve will combine with all actuators.

2. The symbol “—” indicates a combination is not available.
