Each valve seat shall be lifted during the length of the cleaning cycle.
Seat lift durations shall not exceed 10 seconds.
These pneumatic functions include:
1. Upper valve seat lift (takes place during cleaning of upper valve body)
2. Lower valve seat push (takes place during cleaning of lower valve body)
The following chart presents an overview of these functions together with the recommended time durations at 21psi (1.5 bar) CIP
pressure. It is recommended to do seat lift/push in the middle of each step in the CIP sequence.

*Time stated is the actual opening time for the valve. Programmed duration is depended on the access to compressed air and response
time from PLC.
Variations caused by compressed air are typically:
- Long compressed air supply hoses.
- Small ID on air supply hoses.
- Limited availability of compressed air.
