Alfa Laval Unique DV-ST UltraPure diaphragm valve

The Alfa Laval Unique DV-ST UltraPure diaphragm valve meets the requirements of most sterile and ultrahygienic processes. These compact, lightweight valves are modular in design, which enables a wide range of purpose-built configurations.

Parts of the DV-ST range are the T- and Tank-outlet valves. They are available either as machined from block or forged and welded. Using these T-Valve configurations made from forged bodies enables users to cut material and operating costs. The reduction in weight (up to 62% vs conventional block solutions) also reduces stress on the piping. Furthermore, it reduces sterilisation time, while cutting energy costs and system downtime.

The Alfa Laval Unique Diaphragm Valve Premium UltraPure (DV-P) provides more precise flow regulation and gives double the flow rate of conventional diaphragm valve designs at a given pressure drop.

The Alfa Laval DV-P minimises total cost of ownership for diaphragm valves. It cuts energy costs because of double flow rate or lower pressure drop, enabling the use of smaller feed pumps, which require less electricity to operate. Installation costs are also lower than conventional diaphragm valves due to the use of smaller pumps, valves and piping. Further savings are achieved thanks to the extended lifetime of the diaphragm, which results in longer service intervals.
