Exchange the Rotor Seal
5 Remove the rotor seal and isolation seal.
Damage to the rotor seal and cross-port leaks
Before you replace the rotor seal, clean the stator.
Inspect the stator head and swab it with the appropri-
ate solvent. If more stringent cleaning is required, use
a sonicator. Inspect the remaining valve components
for contamination. Clean them as necessary.
If the stator head is scratched, replace it.
6 Install the new rotor seal and isolation seal. Ensure the
metal spring inside the isolation seal faces towards the
valve body.
Make sure that the rotor sealing surface with its engraved
flow passages is facing out. The pattern is asymmetrical to
prevent improper placement.
