Double packing system
In some types of fluids, highly polluting or toxic, a guaranteed external sealing is required, for this we use the “double packing” system. This system consists of two independent closing groups, with an intermediate leak detector, which has been approved by the most demanding end customers, with tests of correct operation of up to 433,000 cycles.
