Alfa Laval’s broad range of diaphragm valves is designed to deliver the utmost reliability in sterile and aseptic applications. The Alfa Laval Unique DV-ST UltraPure is a compact, lightweight valve with a modular design, enabling a wide range of purpose-built configurations. The specified sulphur content is standard for all forged and block valves, safeguarding high quality weldings.
With a pneumatic actuator adjustment of the spring pressure is possible as well as utilization of a stroke limiter. For all handles, over-closure protection in manual operations ensures a defined closing pressure against the diaphragm. Both solutions are optimizing the safety of the sealing functions and prolong diaphragm lifetime.
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. (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 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.
