Observe temperature restrictions on account of approvals.

To prevent the expanded compressed air from freezing, its pressure dew

point must be at least 10 K lower than the medium temperature.

Important information for functional reliability during continuous

operation!

If the equipment is switched off for a long period, it is recom-

mended to activate the valves at least 1-2 per day.

Service life:

High switching frequency and high pressures reduce the service life.

The valves operate maintenance-free.

5.5 Materials

The seal materials depend on the housing materials:

5.6 External control pressure

If valves are designed for auxiliary control air, the compressed air

supply must be connected to port 12 or 14 (control pressure port).

Control pressure: at least 70 % of the operating pressure to

port 1 (minimum control pressure 2.5 bar)
