This company now offers its simple and robust hygienic ball valves with stainless-steel construction (photo), making them easy to flush and clean for compressed air, gases and liquids in the food processing industry. The ball valves were originally developed for use in painting stations, and are therefore completely free of dead zones and easy to clean. These qualities also make them suitable for hygienic applications in food processing. The ball itself is permanently enclosed and sealed by two polytetrafluoroethylene (PTFE) half-liners. The inside of the ball valve and the ball seats are completely free of dead zones and micro-machined to minimal roughness. The stainless-steel ball valves have 1/4-in. threads on both ends. This provides a dead-zone-free interface to the company’s FreeLine connectors or enables direct mounting in installations and lines. — Eisele Pneumatics GmbH & Co. KG, Waiblingen, Germany
