NOTICE!
– Discharge and suction valves differ from each
other!
Only take them apart one after each other, so
that you do not confuse the components!
– Only use new components which fit your valve - both
in terms of shape and chemical resistance!
– Recalibrate the pump after replacing a valve!
– Using an Allen key or similar, insert it into the smaller
hole of the discharge connector and push the valve
inserts out of it.
A suction valve is constructed in almost the same way as a discharge
valve.
Please note, however, that:
n The two valve inserts are identical here
n There is an additional spacer between the valve inserts
n There is a shaped seal in the dosing head instead of an O
-ring
n The flow direction of the suction connector is the opposite of that
of the discharge connector

– On the PVT material version, the ball seat is inte‐
grated in the dosing head and so has to be cleaned
separately!
– On the PVT material version, the discharge valve is
a double ball valve!
