Actuator Mounting
Subsequent mounting of an actuator is possible at any given time and does not require
disassembly of the valve. The actuator is to be executed with a torque in accordance with
the nominal size. The values are to be defined with the manufacturer following a technical
query (pressure, sealing material, media etc.). The couplings must be manufactured in
accordance with the actuator size.
Connection flanges are designed and manufactured in accordance with ISO 5211 as a
standard.
13.1
Fitting the Actuator
When fitting actuators, the requirements of the actuator manufacturer have to be
mandatorily complied with. The manufacturer of the KLINGER Ballostar® KHI assumes
no liability for damage resulting from improper actuator installation. In case of doubt, it is
recommended to discuss every actuator installation with the manufacturer of the actuator
and the valve. Installation work may only be carried out by qualified personnel.
»
Bring ball valve into the "OPEN" position.
»
Mount the coupling element
»
Attach the console to the ball valve (DN 150, DN 200) or mount the actuator
flange on the gear box/actuator (DN 250-DN 1000)
»
Place the actuator in the correct positional arrangement and screw together. If
necessary, bolt.
»
Set the end positions.
»
Function test.
!
CAUTION
With regard to electrical actuators, it must be ensured that the end
positions are limited by the path end switches and not by the torque end
switches.
!
CAUTION
The valve is closed clockwise. It is to be ensured that the 90° movement
is precisely complied with in its OPEN-CLOSED end positions.
