Valve and Actuator Assembly
Selection
Siemens Building Technologies, Inc.
Description
This Technical Bulletin will aid in the selection of a Flowrite 599 Series 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 7 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 8 through 12.
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 Figures 2 and 3, the close-off pressure graphs, to select an actuator. First locate
the graph for 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 assembly needed. Continue to the right to
match the 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 that is a special order.
3. A shaded space with the symbol “X” indicates an inappropriate combination.
