This section contains information about cleaning or replacing valve rotors for the VICI/Valco
Cheminert.
 To clean or replace the valve rotors for VICI/Valco Cheminert
1. Do not remove the valve from the valve drive. For improved access, you may remove all
tubing or the loop.
2. Unscrew the two hex screws, which hold the valve stator to the valve body.
3. Carefully lift out the rotor disk with a protected tool (with tips protected to avoid
scratching the surface).
4. Insert the new rotor. The size-coded positioning tabs prevent you from inserting the rotor
upside down.
5. Tighten the hex screws carefully and evenly to reach a parallel seat of valve stator and
body.
