	Instrumentation Needle Valves
	Parker NP6 Needle Valves are designed with packing below the stem threads and a two-piece stem. The packing below the threads protects the flow stream from thread lubricant contamination or washout and also protects the stem threads from potential damaging effects of the media. The two-piece stem produces a non-rotating lower stem for superior, repeatable sealing and reduced packing wear. (For details, please refer to Parker NP6 Series Products Catalog)
Parker compact SN6 Needle Valves provide shut-off and coarse regulation of liquids and gases utilized in process and instrumentation applications. These rugged valves are manufactured from stainless steel barstock and include integral bonnet designs with packing above the stem threads. (For details, please refer to Parker SN6 Series Products Catalog)
	Parker U Series Union Bonnet Valves have been engineered for use at pressures up to 6,000 (414 bar) and temperatures as high as 1,200 °F (640 °C). A non-ratat lower stem helps to extend packing life by removing rotating from the package area. Stem packing below the threads isolates the threads lubricant from the flow, ensuring adequent lubrincation regardless of the media. (For details, please refer to Parker U Series Products Catalog)
Parker V Needle Valves are designed for positive leak tight shut-off and regulation of fluids in process, power, and instrumentation applications. With a wide variety of port sizes and styles, temperature capabilities ranging from -65 °F to 450 °F (-54 °C to 232 °C) and pressure to 5000 psig (345 bar), V Series Needle Valves provide the user with the utmost in flexibility when designing miniaturized tubing or piping systems. (For details, please refer to Parker V Series Products Catalog)
	Parker VL Needle Valves are excellent for applications involving passive media at moderate pressures. For many, they are the right combination of performance and value. These screwed bonnet designs are manufactured from brass forgings and are standard with PTFE packing below the stem threads. Two PTFE coated stem tip options provide repetitive tight shut-off and/or coarse regulation in both liquid and gaseous service. (For details, please refer to Parker VL Series Products Catalog)
Parker VQ Needle Valves are the right combination of performance and value for manual or pneumatic on-off control in moderate pressure and temperature applications. The manual version employs a toggle handle for quick action at pressures up to 300 psig (21 bar). Compact double acting, normally closed, and normally open pneumatically actuated versions of this valve are ideal for automatic control at pressures up 600 psig (41 bar).
