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
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.
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.
