Installation and Commissioning Regulations for KLINGER PISTON VALVES
(KVN Series)
Please bear in mind the general hazard notes of Klinger valves ( see document wT2792.11....)
Klinger piston valves can be installed in any position in the piping system.
The preferred through flow direction (indicated by an arrow on the body) should, however, be observed.
Note: Before installation protective caps must be removed from both sides of valve body
Attention:
Piston valves show a piston pump effect while closing. This can result in increased pressure
at the inlet side when used in the preferred flow direction. When used with piston pumps and
non-return valves, piston valves should therefore be installed opposed to the preferred
through flow direction (see Fig.1 below).

Direction of flow
No special maintenance is required after commissioning valves with the KX-GT since the rings do not
set like conventional, soft-sealing valve rings.
