Ball Valve's Corrosion-Resistance Suits Pharma Applications
George Fischer, Inc. is expanding its line of valve offerings to include corrosion-resistant products suitable for the pharmaceutical industry.The Type 375 True Union Ball Valve was already offered in PVC for potable water applications; now, CPVC and PPn (natural polypropylene) versions make the valve usable in chemical processing and pharmaceutical manufacturing. The valve is ergonomically designed, with a grooved handle and notched union nut for easy installation. George Fischer says the new valve is pressure-rated up to 225 psi at 68 degrees F, and has a 10,000 cycle life.The valve also includes a safeblock ball seat and blow-out proof stem with double stem seals, intended to provide complete operator protection and maintenance-free operation. A spokesman for George Fischer says the valve handle doubles as a spanner wrench, to adjust or remove the seat carrier for easy disassembly.The valve in PVC and CPVC material is available in sizes 3/8” to 6”, and comes equipped with threaded and socket end connectors; in PPn, the valve is available from 20mm to 90mm (metric socket) and ½” to 2” (NPT).
