Choosing size and type
The maximum flow of the department determines type and combination.
Softened water allows for the use of brass valves, while water from reverse osmosis (RO) requires the
use of corrosion-proof valves.
Surface water with a conductivity less than 50 μS/cm requires the use of corrosion-proof valves.

Pressure release hoses
Important: Discharge hoses from pressure release valves must be conducted to a free outlet. Do not
connect discharge hoses, make sure they run separately. Secure the hoses properly, as they are ex-
posed to strong pressure impacts.
Please note that some of the largest solenoid valve sets require a 1/4" high-pressure hose for pressure
release, while smaller valve sets require a 10/8 mm PA hose.
Surface water with a conductivity less than 50 μS/cm requires the use of corrosion-proof valves.
