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
appropriate 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 the valve.

Install the new rotor seal and isolation seal. Ensure the
metal spring inside the isolation seal faces towards the
valve body.
N O T E
Make sure that the rotor sealing surface with its
engraved flow passages is facing out. The pattern is
asymmetrical to prevent improper placement.
