The H-Series needle valve gives plant engineers the means to improve reliability, and save both money and space, in process and instrumentation applications involving viscous and contaminated media. The valve is available in two forms: as either a discrete hand valve for controlling media flow, or integrated into a monoflange-style manifold for the safe ‘double-block-and-bleed’ connection of instruments to process lines. The large flow path of the 12.7mm valve makes it less prone to blockages or related problems when dealing with viscous and contaminated media. It provides a bubble-tight shutoff mechanism, operation over a temperature range of -55 to 538°C and a Cv value of 2.6. In its standard 316 stainless steel form it is rated for operation at pressures up to 414 barg. The metal to metal sealing meets the firesafe requirements of ISO 10497.
