INSTALLATION OF VALVE
Although KHE ball valves can be pressurised in both flow directions, KLINGER recommends a preferred
mounting direction. The correct mounting direction is marked with an arrow on the valve body. This
ensures that the flange end piece (respective the elastic sealing element) of the ball valve is positioned
upstream.
ATTENTION:
Make sure, that you use the metal part of the hand lever and not the plastic cover to bear
or lift the valve.
MOUNTING OF ACTUATOR
Preparation:
Type and Dimension of the actuator is determined by the required torque for operating the ball valve.
The torque values of valve and actuator can be taken from the torque tables. Attention should be paid to
the operating conditions.
A type plate is not standard
Direct mounting of actuators (as shown on the picture above) is only recommended for temperatures
beneath 80°C. KLINGER recommends to use mounting kits with bracket and coupling, if the
connection-holes of actuator and valve do not match or high operating temperatures occur.
Installation:
•
Turn both valve and actuator into “OPEN”-position.
•
Install actuator in the correct position (
ATTENTION:
valve closes with
counter clock wise
rotation).
Make sure, that the 90° rotation precisely complies with the end positions “OPEN” respective
“CLOSE”.
•
Perform an operational test
Take notice of the actuator position!
(Remember: the actuator has to
be in “OPEN”-position during the
assembly)
