2. Installation and dismantling of actuator
2.1 Installation
Abide by safety measures!
Note: Check again whether the EA is place in accordance with the Chapter “Operation Conditions”. If the
installation conditions are different than recommended it is needed to consult the situation with the producer.
Before starting of mounting the EA onto the valve:
•
Check again whether the EA was not damaged during storing.
•
Check whether the adjusted operating stroke and connecting dimensions of the actuator (see the
nameplate) are in compliance with the valve parameters.
•
In case of inconsonance, perform adjusting according to the part Adjusting of actuator.
2.1.1 Mechanic connection of electric actuator to the armature
EA is by the producer adjusted to parameters according to the nameplate, with connecting
dimensions according to the corresponding dimensional drawing and put it to a mid-position.
Before installation put the hand wheel on.
Mechanical connection with connection dimensions
according to DIN (Fig.3)
•
Properly defat contact surfaces of the EA connecting flange and the
valve.
•
Check the nameplates to assure that actuator and valve strokes are
the same.
•
Set the actuator (A) and the valve (B) to the position ”closed“.
•
Put the actuator (A) onto the valve (B) to have the actuator shaft (3)
leant onto the valve coupling (8).
•
Turn the valve output shaft (5) to connect the stem with the valve
output shaft having the actuator flange (2) sitting on the valve flange
(7).
•
Tighten the screws (4) with the cross system to connect the actuator
flange (2) with the valve flange (7).
•
Check connection dimensions in accordance with Fig. 1.
•
Turn the valve output shaft (5) by one revolution and lock it with the
nut (6) (to create pre-stressing against the valve seat).
