Aseptic Diaphragm Valves
     Alfa Laval offers an extensive range of aseptic diaphragm valves for ultra-hygienic processes. The diaphragm valve is the most commonly used valve in the pharmaceutical industry, but it is also an ideal alternative for other aseptic applications. The Alfa Laval Aseptic Diaphragm Valve is a weir type diaphragm valve. With its modular design, composed of: valve body, diaphragm and actuator, it enables the realization of special designs and needs with high quality and well-proven standard components. It can be combined in a number of configurations and executions but the most typical is a two-way valve offering an on/off function. The Aseptic Diaphragm Valve is available both with manual and pneumatic actuators with a number of options. 

     The diaphragm is the critical part of the valve. In the Alfa Laval range there are both soft and hard compounds each suitable for their specific applications. The soft material diaphragm is EPDM which also is available in EPDM with a Kevlar core when extra mechanical stability is required. The hard diaphragm is PTFE with either EPDM or Silicone as a backing plate. For the pneumatic actuators Alfa Laval also offers an externsive range of automation units, including control units, position indicators, seal adjusters and stroke limiters. Apart from the standard two-way valve Alfa Laval also offers tank outlet valves, T valves and GMP/SAP valves in a wide range of dimensions and configurations.
