New 2- and 3-way TDV tube diverter by DMN-Westinghouse
Design based on construction of M-TDV mulitport diverter
Contrary to the M-TDV multi-port 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.
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. 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.
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.
