8.6.3.1 Replacing valve membranes
Correct assembly procedure of the housing and membrane is essential for proper
function and preventing future leaks.
Procedure
1) Place the membrane in the valve housing with the seam on the periphery of the
silicone membrane facing from the magnet of the valve, see picture below in
Section 8.6.3.2 “Valve mounting tool K15391C” on page208.
2) Tighten the screws with a torque of approximately 0.7 Nm. Make sure that self
locking nuts are used.
Results

Do not over tighten the screws, this will deform the valve housing and cause
leakage.
