The ball valves are classified as “Pressure accessories” in the sense of PED Directive 2014/68/EU, Article 2, paragraph 5 and are subject of Article 4, paragraph 1, letter (c), of the same Directive. All the products range is suitable for use with refrigerant R744 (CO2), classified in Article 13, paragraph 1, letter (b), of PED Directive 2014/68/EU as part of Group 2, therefore not toxic, not inflammable and not explosive fluid and indicated in A1 Group of Annex E of standard EN 378-1.

The valves are specifically designed to guarantee maximum safety both during operation and during system stops. On the sphere, in addition to the main passage hole, there is a relief hole that prevents any pressure increase due to the volumetric expansion of possible liquid trapped inside the sphere when it is closed. The innovative design allows rotation of 180° the position of the relief hole which must always be towards the high-pressure side for an optimal seal guarantee. This solution allows maximum flexibility of use, thus simplifying both the system design phase and the maintenance operations. The valves are approved for use in all parts of the system with pressure values equal to or less than the maximum working pressure indicated, typically: the liquid line, suction line and gas bypass line.
