Sanitary ball valves are generally used on the utility side of processing – for example caustics delivered to a CIP skid to formulate recipes for cleaning product lines, processing plant steam, and bulk utility supplies. The design and operatio of ball valves makes them unsuitable for product contact surfaces, but can be required at certain points for installations when higher pressure is required. In these cases the ball valve materials of construction are critical, as with any high purity component. The Carten SBV series utilises high TFM1600 polymer material for contact seats and seals, and CF3M/S31603 (316L) high grade stainless steel for all media contact surfaces – therefore biocompatibility is assured. In addition the high grade of mateirals utilised allows installation in the most aggressive CIP and SIP conditions.
