The benefits and applications of this series made of high-alloyed stainless steel begin, where versions made of gunmetal are at their limits. The flexibility of the various versions offer the optimal configuration for every application.
In addition to the basic version the numerous sealing possibilities and materials, back-pressure compensating metal bellows and / or a gastight cap offer the necessary optional extras required to fulfill the highest safety requirements.
