5.3 Cleaning connection
Connection for the hose
1 ", DN 25 Ø 4/6 mm
DN 40...100 Ø 8/6 mm
1.5"...4" OD; 2''...4'' IPS Ø 8/6 mm
DN 125, 150; 6" IPS; 6'' OD Ø 10/8 mm
Service pressure for the optimal cleaning
•
min. 2 bar (29 psi)
• max. 5 bar (72.5 psi)
The duration of the rinsing operation via the rinsing valve depends on the type of
soiling and typically ranges between 10 and 60 seconds.
The durability of the components of the cleaning connection (sealing disc,
support sleeve, PTFE hose) is dependent on the style, pressure and temperature
of the required medium.
