3.1.2 Type “A” Bases: Thrust-only Applications
Standard A1/A1E Base
The standard MX actuator thrust base is the A1, and may be bolted directly to the actuator. The thrust base contains a
bronze alloy thrust nut that may be machined to suit the valve stem.
An A1E (extended) thrust nut can be provided and may be installed to reach shorter stems.

Disassembly of the main housing from the base may be recommended to allow the base to remain on the valve if the
actuator must be removed for service.
