Installation
Ball valve series
FK 75C
and
FK 76C
are usually intended to be connected to pipework with matching flange
connection.
The ball valve is designed for use under normal load in the pipework. Particular operating conditions must be clearly specified
in the customer requisition/inquiry. In the case of deviations from these conditions, Flowserve must be consulted.
5.1
Preparation for Installation
The following points must be observed before installation:
Pipework must be strong enough to safely bear the ball valve and its accessories. Verify if special support
is needed for the unit.
Pipework must be cleaned before installation.
There must be sufficient clearance above and to the side of the valve and/or attachments to permit
maintenance, inspection or repair work without any risk.
Extensions and attachments that are used for heat removal or heating must not be insulated.
If the ball valve is intended for regular manual operation, then a standing area must be provided for the
operator on which the latter can safely apply the necessary forces in accordance with applicable user,
local and national standards as well as guidelines.
Observe possible flow direction!
For unidirectional ball valves (special
case), the flow direction is indicated by an arrow on the body.
