4.3 Cleaning systems
The standardised design of fittings makes it
possible to mount FC20 cleaning systems
directly. The 4-hole types are especially
designed for these applications.
The Yokogawa program includes two
different types of cleaning systems
(see figure 4.3):
- brush cleaning
(electrically or pneumatically driven)
- chemical cleaning
