4. Installing the valve
WARNING:
Incorrect installation may lead to severe personal injury and may damage the product
or cause it to malfunction. For this reason, these instructions must be followed carefully
when the valve is installed.
These instructions are general instructions, and they do not cover every possible usage
condition. If you require further guidance related to using the valve or additional informa-
tion on its suitability for the intended application, contact the manufacturer.
· M- and V-profile press jaws are suitable for pressing.
· The compressive force of the press tool for pressing the 18–35 mm size valves must be at least 19 kN.
· Loop-type press jaws are recommend for pressing the 42 mm and 54 mm sizes, and the compressive
force of the press tool must be at least 32 kN.
· The protective covers for the flow openings must only be removed immediately before installation. The
valve should be protected from sand, dust and other impurities.
· Take great care when you test the valve before fitting it to the pipe network.
· The valve must not be lifted by the handle or precision control knop. Dropping the valve or lifting it
incorrectly may lead to severe personal injury or product damage.
Note:
The valve should only be used in the applications for which it is intended.
Immediately before installation:
· Remove the protective covers for the flow openings (shut-off valve) and check that the internal surfaces
of the valve are clean and the leak before press (LBP) O-rings at the ends of the press connection are
in place and undamaged.
WARNING:
The end of the pipe to be connected must be cut straight and all sharp burrs must be
removed carefully from the external and internal surfaces. Any impurities in the valve or
pipe could damage the valve or its coupling heads.
