3. Installation and dismantling of actuator
3.1 Installation
Abide by safety measures!
Note:
Check again if placement of EA reply to chapter "Operation conditions". In case that operation conditions
are different from recommended, consultation with producer is needed.
Before starting of mounting the EA onto the valve:
• Check again whether the EA was not damaged during storing.
• Check whether the adjusted operation 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 "Adjustment“.
3.1.1 Mechanical connection
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.
