Pipe connection
Avoid leakage:
• Install fittings as per ISO 7-1. Ball valves (internal threading) = "Rp";
Piping (external threading) = "R".
• Do not use too much hemp or PTFE tape.
• Do not tighten pipe threading to the very end.
• Place the pliers/wrench on the ball valve union nut that is closer to the pipe to be
tightened or loosened.
Flow direction
Make sure that the valve is mounted in the proper flow direction. A symbol is applied to
the ball valve body:
