Parker Instrumentation has launched ball and needle instrumentation valves optimised for high-pressure fluid control applications operating at up to 1379 bar. The valves meet the needs of high-pressure hydraulic control and other demanding instrumentation applications that are increasingly being faced in the offshore oil and gas sector.

The ball and needle valves — the 20K Hi-Pro ball valve and the 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 9/16", or 6, 8, 10 and 12 mm tube connections, the valves’ 6 mm 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 utilises a two-piece construction, reducing potential leak paths. It is fully bidirectional and is actuated by a 90° turn for fast on/off action. An integral gland adjuster is secured by means of Parker’s Tru-Loc mechanism. The valve mechanism works on the floating ball principle and offers 100% bubble-tight operation. PEEK seat material is utilised to allow operation over a wide temperature range from -20 to +200°C.

The 20K H-Series needle valve has a multi-turn action, which provides a fine flow control mechanism. The valve’s metal seat allows operation over a wide temperature range from -54 to +200°C.

The valves are available with Phastite connectors. Compared with cone and thread ends, a valve fitted with Phastite connectors provides a number of major benefits. It reduces assembly time as a seal is made in seconds by pushing the Phastite collar along the tube using a handheld hydraulic tool. As the collar moves it forces profiles on the internal sleeve to bite, providing a high-pressure, leak-tight seal.
