PN9000 series selection guide: Before making your PN9000 series selection please reference pages 6 to 26 - 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.
