1 Page 1 of 5 TI-P CH Issue 1 PN9400 Series ISO 9001 Pneumatic Actuators for SPIRA-TROL K and L Series Control Valves Cert. No. LRQ Description The PN9400 series actuators are a compact range of linear actuators that are available with a single operating diaphragm size for matching the requirements of DN125 to DN200 SPIRA-TROL valves at various differential pressures. Each actuator is fitted with a mechanical travel indicator and incorporates a fully-rolling diaphragm, which provides good linearity over the operating stroke. Technical data Temperature range -40 C to + 80 C Maximum operating inlet pressure Air supply connection Actuator travel 6 bar g ¾" NPT 80 mm Available types PN = Standard Optional extra Manual handwheel Suffix E = Spring-extend Suffix R = Spring-retract Suffix H J G H F Dimensions and weights (approximate) in mm and kg Actuator F G H J Actuator Weight with handwheel PN9400E and variants PN9400R and variants Local regulations may restrict the use of this product to below the conditions quoted.

4 Page 4 of 5 How to use the sizing data: The following tables supply guidance as to the sizing of the PN9400 when it is used on the SPIRA-TROL K and L series valves. Two conditions are illustrated in tabular form: Class IV shut-off - Providing shut-off of the valve to the requirements of BS (IEC ) Class IV. Class VI shut-off - Providing shut-off of the valve to the requirements of BS (IEC ) 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.
