In order to design valves for a process system correctly, the valve size is determined by the required flow rate. The Kv-value serves as a calculation basis for the different process conditions. This value is stated in the following table with regard to nominal diameter and standards. Kv-value The Kv-value is a parameter defining the flow rate of valves. It describes the amount of water from 5° to 30°C which flows through the valve at a pressure loss of 1 bar. The Kvs-value describes the Kv-value when the valve is 100% open. 73 .2 C m (0 ™ I O -t-J 4-o c D “ "5 ® O i-Conversion: For the...

Surface Finish The consistency of the interior surface has a great impact on the quality of an aseptic system process. By means of polishing, the interior contact surface is reduced. The specified surface quality of the valve body is achieved through mechanical polishing and electro polishing. According to the standards SED offers surfaces with a surface finish up to a quality of 0,25 µm and 10 Ra. At SED the stated surface finish always describes the maximum surface roughness value. The surface finish is reached by automatic or manual mechanical polish processing. The methods that are...

Ra-Value The arithmetic average Ra is used as parameter for the surface finish profile. L t = 5,6 mm traversing length and l n = 4,0 mm measuring range split in 5 single measuring sections l r = 0,8 mm each measured transverse to the polished image. Definition of the SED codes for Ra-Values

The diaphragm is the most important component of the diaphragm valve. Besides the valve body, the diaphragm is the only part which contacts the process medium. The diaphragm separates the process medium from the actuator or top works and the external atmosphere. In addition the diaphragm is the dynamic part which the flow rate of the process medium is controlled and stopped. The developing of formulation of compound is done closely with a specialised company developing, producing and testing compounds since many years together with SED for our market. The SED diaphragms have been developed...
