* Please note that although the AEL6321- and the AEL6323- have the same maximum differential pressure values, they have different

operating speeds. The same applies to the AEL6421- and the AEL6422-. Please refer to the technical data table on page 1 for full details.

Safety information, installation and

maintenance

For full details see the Installation and Maintenance Instructions

that are supplied with the product.

Installation and wiring note:

The valve should be installed in a horizontal pipeline. The position

of the actuator will depend on the type of valve to which it is fitted

and the temperature of the media. However, it is not recommended

that the actuators be fitted at more than 90° from the vertical

position or in a wet environment.
