Parker Instrumentation has launched ball and needle instrumentation valves optimized for high pressure fluid control applications operating at up to 20,000PSI. The ball and needle valves – 20K Hi-Pro ball valve and 20K H-Series needle valve – are fabricated from 316 stainless steel as standard, and offered in NACE (corrosion) compliant and HCT (heat code traceable) versions. Available with 1/4, 3/8 or 9/16in, or 6, 8, 10 and 12mm tube connections, the valves’ 6mm bore sizes provide maximum flow rates (Cv) of 0.66 for the needle version, and 1.56 for the ball valve. The 20K Hi-Pro ball valve uses a two-piece construction, reducing potential leak paths. It is fully bidirectional and is actuated by a 90 degree turn for fast on/off action, with stops for positive user feedback. The 20K H-Series needle valve has a multi-turn action, which provides a fine flow control mechanism. An integral gland adjuster is secured by means of Parker’s proprietary Tru-Loc mechanism. The valve’s metal seat allows operation over a wide temperature range from -54 to +200C. The valves are available configured with Parker’s high-pressure Phastite® tube connector ends and are suitable for higher pressure hydraulic control and other demanding instrumentation applications in the offshore oil and gas sector.
