Introduction new 2/3TDV tube diverter from DMN-WESTINGHOUSE

DMN-WESTINGHOUSE have recently introduced their new 2- and 3-way TDV tube diverter. As the existing TDV type was due for re-evaluation, it was thus decided to design and produce a 2- and 3-way diverter of similar construction to the M-TDV multiport diverter. The M-TDV is available with 4 up to 24 ports on the smaller pipe sizes, therefore the new 2- and 3-TDV seamlessly connect with the M-TDV range. DMN already has a two way tube type diverter which has been in its product offering since 1996 and was due for re-evaluation with regard to the requirements of today. New features Contrary to the M-TDV with electric drive, both the new 2- and 3-TDV are activated using a pneumatic actuator, which is more cost effective. This gives a very compact design to both diverters and by using an additional line cylinder on the 3-TDV very accurate positioning is achieved. The uniquely designed seal that has already been proven on the M-TDV is also being used on the new 2- and 3-TDV. This seal is made from EPDM and is very easy to fit and clean, and being inflatable guarantees absolutely tight sealing in the conveying line up to 3 bar g. (higher on request) This also applies to liquids. No leakage The whole range of tube diverters (2-, 3- and M-TDV) are of a sanitary design and have stainless steel AISI 316 product contact parts with a multiple choice of line connections, ranging from a simple pipe connection to a milk coupling. The swan neck pipe connecting the inlet to outlets is designed to give minimum product degradation in every conveying direction. All conveying lines that are not in use are also sealed at the diverter outlet. This ensures that there is no air or product leakage from destinations that are not being used. Cleaning The diverters are designed to be easily removed from the line for cleaning (COP – cleaning out of place). It is also possible to purge the individual conveying lines with a cleaning liquid without removing the diverter from the line (CIP – cleaning in place). Removal from the line is only necessary when a complete cleaning operation is required. This gives the customer the option to chose a cleaning method tailored to suit their process. There will also be a very competitive 2-TDV 1 bar hybrid design available, constructed out of aluminium and stainless steel, having all product contact parts made from stainless steel and using a static silicon seal instead of the inflatable EPDM.
