DEPRESSION VALVES

The depression valves, art. 0810/0811, with free suction, are specially made for agricultural use on tanks for sewage transport and on vacuum trucks as safety valves, to avoid the implosion of the tank itself during the suction phase.

The wide bell permits to limit damages due to atmospheric conditions and to avoid the settling debris, in addition the possibility of the manual opening permits to check the functionality of the valve itself.
