    APV_DKR2 ATEX_UK-0_022018.indd Identification of valves, Temperature classes, Responsibilities 3.3 Responsibilites It is within the operator`s responsibility to ensure that the specified product temperatures are not exceeded and that regular inspections and maintenance are carried out to provide for proper function of the valve. Intended Use The intended use as field of application of the butterfly valves is the shut-off of line sections, especially in beverage and food installations.
  • Page 12 APV_DKR2 ATEX_UK-0_022018.indd Mode of Operation 5.1. General terms Due to the use of high-quality stainless steel and seal materials complying with the specified requirements, the double seat ball valve DELTA DKR2 can be used in the food and beverage industries as well as in the chemical and pharmaceutical industries.

  • Page 13: Mode Of Operation

    APV_DKR2 ATEX_UK-0_022018.indd Mode of Operation 5.2. Potential Equalization A possible risk may result from a potential difference between the components. With non-conducting media or empty pipline sections, a conducting connection must be created between the valve components. With double seat ball valves, this is reached by the installation of a spring.

  • Page 14: Cleaning

    APV_DKR2 ATEX_UK-0_022018.indd Cleaning 6.1. Cleaning recommendation The valve passage is cleaned by the cleaning liquid during cleaning of the connected pipelines. Several switching (“cycling”) of the valve during pipeline cleaning is beneficial for the cleaning of the leakage chamber. Depending on the degree and contents of soiling, the cleaning liquids, times and processes for the individual application must be scheduled.

    APV_DKR2 ATEX_UK-0_022018.indd Installation 7.1. Welding Instructions Welding may only be carried out by certified welders (DIN EN ISO 9606-1). (seam quality DIN EN ISO 5817). The welding of the mating flanges must be effected in such a way that deformation strain cannot be transfered to the valve body. TIG orbital welding is the most appropriate method. Before welding, all heat sensitive parts of the valve must be removed! Dismantle valve ball housing with seals between the counterflanges.
