Etna Pa2-Pa2V (Relief - Non-Relief) Pressure Switch

Etna Pa2-Pa2V (With/Without Discharge) 3 - 11 Bar Pressure Switch

General features

• PA type pressure switches are designed to automatically start and stop the booster and water pumps.

• PA-V type ETNA pressure switches, on the other hand, are manufactured in a way to ensure the evacuation of the air in the pressure pipe when the compressor stops, in order to facilitate the start-up of the air compressors under pressure.

• Pressure switches with discharge are used in air compressors, pressure switches without discharge are used in booster. • The three-way safety adapter allows the pressure gauge and safety valve to be mounted directly on the switch without the need for any other equipment.

• The stopping pressure of PA-1 type pressure switches can be adjusted between 2.5 Atu and 5 Atu, and the operating pressure can be adjusted between 0.5 and 3.9 Atu depending on the stopping pressure.

• The stopping pressure of PA-2 type pressure switches can be adjusted between 7 Atu and 11 Atu, and the operating pressure can be adjusted between 3 and 9 Atu depending on the stopping pressure.

• The stopping pressure of PA-3 type pressure switches can be adjusted between 11 Atu and 16 Atu, and the operating pressure can be adjusted between 4 and 13 Atu depending on the stopping pressure.

• The stop pressure of PA-4 type pressure switch can be adjusted between 4 Atu and 8 Atu, and the operating pressure can be adjusted between 1 and 7 Atu according to the stopping pressure.
