Description

This Technical Bulletin aids in selecting a 599 Series Zone Valve and an electronic

actuator or Thermic actuator assembly.

Figure 1 provides a graph of water capacity for selecting the proper valve size. Tables

1, 2 and 3 provide maximum water capacity and close-off pressures for assistance in

the selection of a valve and actuator according to specifications.

Tables 4 and 5 identify the electronic actuator/valve assembly product numbers. Table

9 identifies the Thermic actuator/valve assembly product numbers. The tables show all

possible combinations of Zone Valves and compatible actuators that can be ordered as

complete valve/actuator assemblies from the factory.

Table 6 contains the dimensions of all valves. Tables 7, 8 and 10 provide the

dimensions and service envelopes required for each valve/actuator assembly.

Using the Valve and

Actuator Selection

Graph

Use Figure 1, the Water Capacity Graph, to select a valve size as follows:

1. Locate the specified flow rate on the vertical axis.

2. Follow across on the horizontal axis to the point of intersection with the specified

pressure drop.

3. Choose the valve size from the heavy diagonal lines across the graph.

See Table 3 to find the close-off pressures for valves relative to their size.

Using the Valve and

Actuator Assembly

Tables

Use the Product Number Tables 4, 5 and 9 to select a valve and actuator assembly as

follows:

Read the tables from left to right and select the appropriate valve specifications to

identify the row with the required valve body.

1. Read across the top of the tables and select the appropriate actuator specifications

to identify the column with the required actuator.

2. Read down the actuator column and read across the valve body row. The

column/row intersection determines the appropriate valve and actuator assembly.

The valve and actuator assembly product number is the actuator prefix code added

to the valve body suffix.

Technical Bulletin TB254 Document Number 155-291 February 9, 2018 Selection Examples Specifications 599 Series Zone Valve and Actuator Assembly Selection In an ANSI 125 piping system, a two-way, normally closed, female-by-female, NPT 3 threaded valve delivers 6 gpm (0.52 m /hr) chilled water with no more than 6-psi (41.4 kPa) pressure drop across the fully open valve. The actuator shall receive 120 Vac power; accept a two-position control signal, and provide normally closed operation.
