This butterfly valve has a PTFE lining

This leading manufacturer of plastic-lined valves and process pumps has expanded its product range of shut-off and control butterfly valves. The company now offers valves with a PTFE disc/stem unit to DN 750 (30 in.) or with a metallic disc/stem unit up to DN 1000 (40 in.). The body lining is made of PTFE. The valves are soft-sealing and gas tight (both lined and metallic versions), and can be used for operating pressures of 0.1 mbar vacuum up to 10 bars and at operating temperatures of –40 to 200°C. The wetted materials are FDA-compliant (U.S. Food and Drug Admin.), and therefore also suitable for use in food processing, pharmaceutical and other sectors. The version with the metallic disc/stem unit is also suitable for free-flowing bulk materials. — Richter Chemie-Technik GmbH, Kempen, Germany
