These valves are designed for maximum safety and operating simplicity. They were the first valves that were easy to assemble and disassemble, and today they are still the ones most imitated. Their outstanding and well consolidated reputation for performance, reliability and ruggedness is further enriched by their practical, anatomical design, which permits easier handling. The shape of the knob provides a firmer grip and facilitates tank opening and closing. The very convenient connection can be quickly changed from the international to DIN type. All these characteristics have permitted the Cressi-sub valves to meet all the strict tests called for by the European norms, thereby, receive the prestigious CE certification.
