PN9000 series selection guide:

Before making your PN9000 series selection please reference pages 4 to 27 - Sizing data

How to use the sizing data:

The tables supply guidance as to the sizing of the PN9000 when it is used on a SPIRA-TROL control valve.

Two conditions are illustrated in tabular form:

Class IV shut-off - Providing shut-off of the valve to the requirements of BS 5793-4 (IEC 60534-4) class IV.

Class VI shut-off - Providing shut-off of the valve to the requirements of BS 5793-4 (IEC 60534-4) class VI.

To select a suitable actuator:

-

Identify the column containing the valve and gland material selected.

-

Identify the maximum operating pressure condition, including any transient pressures likely to occur, within the selected column.

-

Read back to the left hand side of the table to identify the suitable actuator for the application.

For conditions outside of those illustrated please contact Spirax Sarco.
