Control valves
Electric actuators
How to use the sizing data:
The following tables supply guidance as to the sizing of the AEL6 series actuator when it is used on the Spira-trolTM K and L series valves.
Three conditions are illustrated in tabular form:
KE, LE, KEA - 2-port valve: Class IV shut-off - Providing shut-off of the valve to the requirements of BS 5793-4 (IEC 60534-4)
class IV.
KE, LE, KEA - 2-port valve: Class VI shut-off - Providing shut-off of the valve to the requirements of BS 5793-4 (IEC 60534-4)
class VI.
QL - 3-port valve: Class IV shut-off - Providing shut-off of the valve to the requirements of BS 5793-4 (IEC 60534-4) class IV.
To select a suitable actuator:
- Identify the column containing the valve size 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.
Maximum differential pressures for modulating duties only –
KE, LE, KEA and LEA 2-port valves.
For pure control applications providing control across the full valve operating range, but not guaranteeing shut-off to a greater level than
the minimum flowrate based on the valve 50:1 turndown.
