Danger to life! Actuators which are no longer used or defective must be diposed in professional manner. Defective actuators must be returned to your SPX FLOW representative for their professional disposal and free of charge for you. Please address to your local SPX FLOW representative.
APV_DA3+_ATEX_UK-0_022018.indd Safety Instructions Installation, connection, start-up, maintenance and repair work must only be carried out by qualified personnel. The following aspects must be observed: The instructions of this manual together with all relevant instructions for the components, equipment and installations installed. Warnings and installations fixed to the components. The specific regulations for and requirements to the system in which the valve is installed. The currently valid regional, national and international regulations.
All data (temperature classes) refer to an ambient temperature of 0°C and 40°C. If the ambient temperature is above 40°C, the temperature difference must be adjusted. In all cases, contact your responsible SPX FLOW representative! Double seat valve DELTA DA3+ - ATEX...

APV_DA3+_ATEX_UK-0_022018.indd Mode of Operation 5.1. General Terms DA3 double seat valve Due to its construction and mode of operation as well as to the use of high quality stainless steel and adequate seal materials, the seat lift actuator double seat mixproof valve DELTA DA3 is suited for applications in the food and beverage industries as well as in the pharmaceutical and chemical industries.
APV_DA3+_ATEX_UK-0_022018.indd Mode of Operation fig. 5.2. 5.2. Valve in “closed” position The lower and upper valve shafts are closed by spring force and safely separate the different fluids A and B. The leakage chamber L which is situated between the two valve shafts, provides for a free and absolutely depressurized discharge to the bottom. The valve shafts are balanced and, thus, safe against pressure hammers.
APV_DA3+_ATEX_UK-0_022018.indd Auxiliary Equipment 6.1. Valve position indication fig. 6.1. Proximity switches to signal the limit position of the valve shafts can be installed at the actuator if requested (fig. 6.1.) D1 = valve position "closed" D2 = valve position "open" (DN 40 - 50, 1,5” - 2” only) D3 = valve position "open"...
APV_DA3+_ATEX_UK-0_022018.indd Cleaning 7.3. The leakage chamber (fig. 7.3.) The cleaning of the leakage chamber is undertaken by CIP spraying. CIP cleaning connection (C). fig. 7.3. The valve shafts being lifted, the CIP liquid also cleans the leakage chamber. The spraying does not produce pressure build-up in the leakage chamber and can be carried out in closed and in open valve position.

Cleaning of upper area (fig. 7.6.) The upper valve shaft is lifted via the connection A2 = By lifting of the upper valve shaft, the cleaning liquid flushes over the upper seat seal and the upper valve seat into the leakage chamber and cleans this area.
APV_DA3+_ATEX_UK-0_022018.indd Installation 8.1. General Terms The valve must be installed in vertical position. Fluids are, therefore, freely drainable from the valve housing and the leakage chamber. Valve housings can be welded direct into the pipelines (completely dismantable valve insert). Conductive connection to the pipeline must be provided. The integration into the internal potential equalisation must be guaranteed! A ttention: Observe welding instructions.
