Replace the PV1 pinch valve seal
1. Remove the eight M12 screws and nuts, and then remove the two flanges from the pinch valve
housing.
2. Pull the pinch valve seal out of the pinch valve housing.
3. Examine the tapered surfaces on the pinch valve flanges and housing. Tapered surfaces
should be smooth (paint discoloration is okay) with no grooves or pitting. Replace the pinch
valve flange if the tapered surfaces have damage. Replace the pinch valve if needed.
4. Clean the tapered surfaces with a lint-free rag. The surfaces must be clean before installing the
new pinch valve seal.
