Valves for Specialist Pigging Equipment AKO Pinch Valves Last 8 Years to date without Failures A division of a large company producing specialist ice pigging equipment have successfully been using AKO Pinch Valves for 8 years. Pigging is the practice of cleaning a pipeline using devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is carried out without stopping the flow of the product in the pipeline. For their ice production system, this company required a method of dynamic throttling, and therefore sourced Pinch Valves from AKO UK. The type of Pinch Valve used is from the VMC stainless steel range. It is 10mm in diameter and has an EPDM white food quality rubber sleeve rated to 120’C. Either side of the valve are threaded spigot RJT ends. Within the 8 years of using AKO Pinch Valves, the company have never needed to replace a rubber sleeve.
