Environment

M1500

M1500A

Cause

Why has the "A" been dropped from the specification number?

Resolution

Originally there were two specifications;

M1500A which fitted to the control valve using a "U-Bolt".

M1500A-VB which fitted to the valve using a "Screw Mount".

The M1500 actuator is fitted to the valve using an "U-Bolt", if a "Screw Mount" is required, then the appropriate linkage kit should be used.
