6. Valve Design
The EA ¢1 electrical actuator can be mounted on
ball valves type 546, DN10–50, by using the cor-
rect coupling piece and selecting a suitable adap-
ter plate with clamps.
The actuators are supplied ex works in the «open»
position. See Section 6.¢ for the individual assembly
components required for the ball valve type ¢07.
Both end positions in the actuator have been preset
in the factory. It is necessary to readjust these after
installation at the customer (see Section 7).
How to assemble (see Fig. 6.1)
Screw the adapter plate with the fixed clamps
tightly onto the actuator (note the cam positions).
Mount the multifunctional module on the ball valve.
