Safety valve made of stainless steel, angle-type 

Particularly high demands are placed on the cleanability of equipment in the food and pharmaceutical sectors and thus on the design of equipment parts without dead space. These principles have been implemented in the development of the new 4040 series.

Manufactured from fully forged stainless steel and with the usual slim and compact design. With a very smooth surface of Ra < 0.76µm, all medium residues can be removed perfectly.
