Parker Instrumentation is adding a 25mm version to its Hi Pro instrumentation ball valve family. Featuring a novel two-piece construction that reduces potential leak paths to a minimum, and a design optimized for reliability, the new valve is ideal for long-lifecycle applications in offshore environments. The new high flow rate option extends the application scope for Parker’s valve family from instrumentation applications into areas such as isolation on process lines, and vessel draining and venting. The ability to specify the valve with a choice of end connections including integral compression tube fittings also makes it suitable for hydraulic power applications. The new, fully bidirectional Hi Pro valve is initially available in 316 or duplex steel. The design conforms to ANSI/ASME ratings and features a 4:1 pressure boundary safety factor, to deliver reliable ANSI Class 1500 operation. It meets the firesafe requirements of API 607 and BS6755 Part 2. The valve’s
body end connector thread is additionally fitted with an environmental seal, protecting it from external corrosion attack. The valve mechanism works on the floating ball principle, with dynamic response seats and an anti blow-out stem, and offers 100% bubble tight operation.
