test for leak-tightness / valve function
Warning!
danger of injury through egress of flow medium.
▶ Tighten the body screws / nuts sufficiently.
Applying an unnecessary degree of force to tighten the
body screws / nuts leads to increased wear and therefore
shortens the service life of the diaphragm.
If the valve leaks when the medium pressure rises:
→
Tighten the diagonally opposed body screws / nuts by a one-
eighth turn until the valve no longer leaks.
This procedure ensures that the diaphragm and the pressure piece
are optimally aligned to each other and the valve function is ensured.
→
Switch the valve several times and if necessary tighten the body
screws / nuts more.
