Installation & Operating Instructions
Ball Valve FK 75C and FK 76C
Installation
Safety instructions relating to the pipework system (including fittings) are
to be provided by the operator.
Design-relevant pressure and temperature fluctuations must be inquired
with the manufacturer.
The flanges used are standard flanges (e. g. standard flanges per
ASME B16.5). The tightening torques of the bolts must be determined
according to the standard flange connection.
After completion of the assembly
– before the ball valve is actuated – a
flushing of the pipeline system is recommended.
If pipework forces are transferred to the valve, then the design must be
inquired with the manufacturer accordingly.
If the ball valve is intended to serve as permanent shut-off from the
atmosphere, a blank flange or equivalent end must be provided by the
end user.
5.3
Actuator Mounting / Orientation of the Valve-Actuator Unit
Actuators are usually installed above the ball valve. The shaft connection is in a vertical position. Other installation
orientations are possible according to the evaluation of the specific conditions.
If in doubt, please consult Flowserve.
In case of heavy and/or asymmetrical actuators or with units which are
not installed vertically, bending and/or torsional forces can occur
–
especially on extended stems with a stuffing box.
Support of the actuator in the installed position may be required.
Additionally, in the case of critical vibrations or impacts during operation,
it can be useful to additionally support the actuator or provide shock
absorption.
