For use in hostile and corrosive conditions, or for food processing and other clean-room environments, Castell Iso-Lok now produces key products in hygienic, easy-to-clean, high-polish stainless steel. The company has introduced a stainless steel version of the its Multi-Clasp, a range of fully stainless steel padlocks, and stainless steel versions of its V-Safe valve cover. The stainless steel products are suitable for use in hygienic areas, providing additional protection against harsh environments. They can be used when wet and dusty environments are problematic, and can be used at sea or where acids and other chemicals are present. The stainless steel Multi-Clasp can be used to safely lock machine controls, isolators and circuit breakers. The fully stainless steel padlocks are believed to be the first of their kind in the world. The body, shackle and even the unique, patented locking mechanism, which features no springs, are all made from grade 316 stainless steel. The stainless steel version of the V-Safe valve cover is designed to offer greater safety and security. This “Tamper Proof” device secures the regulation of liquids and gases by protecting wheel-operated valves against inadvertent or unauthorised operation. Perforations in the edges reduce weight and prevent the build up of fugitive emissions.
