Flow Switch With Pipe Section; Flow Switch For Direct Installation - SIKA VH Série Notice D'utilisation

VH... / VK...
 When installing and before starting-up, it is to be guaranteed that the mechanical proc-
ess connections are technically tight.
 Always consider the impermeability of the screwing elements for the zone allocation.
Depending on the operating conditions, it may be necessary to regularly check the im-
permeability of the screwing elements.

4.2 Flow switch with pipe section

 Install the flow switch pipe section just like a valve in the existing pipe.
 Sealing of the brass or stainless steel pipe sections has to be carried out with either
thread sealants (Teflon tape, surface coating, etc.) or via sealing rings on the face of the
tube section.
 Flow switches optionally equipped with a copper tube section ( Fig. 5) have to be sol-
dered to the pipe. The flow switch (body with paddle system) and the o-ring have to be
disassembled from the tube section.
 With version ...MKU seal the PVC tube section ( Fig. 6) in the pipe using suitable adhe-
sive joints.
