Parker V Series Brass Needle Valve, Inline, T-Bar Handle, Needle Stem, 1/2' NPT Female: Industrial Needle Valves: Industrial & Scientific. Parker V Series Brass Needle Valve, Inline, T-Bar Handle, Needle Stem, 1/2" NPT Female: Industrial Needle Valves: Industrial & Scientific. This V series inline needle valve has a brass body, aluminum T-bar handle, needle stem, integral bonnet, and female National Pipe Taper (NPT) threads on both ends to connect two male threaded pipes going in the same direction. The brass body offers higher corrosion resistance than steel. Operating temperatures range from -6 to +00 degrees F (- to +0 degrees C) at up to 3,000 pounds per square inch gauge (psig) CWP (cold working pressure). The integral bonnet is forged as a part of the valve body and provides strength. The regulating needle stem type N, made of 316 stainless steel, conforms to ASTM International (ASTM) A76 standards for stainless steel bars and shapes, and it provides coarse regulation with metal-to-metal shut-off in liquids. The aluminum T-bar handle resists corrosion and tarnishing, and it allows greater torque than a hand wheel. PTFE (polytetrafluoroethylene) packing, which is located above the power threads, is suitable for use with most liquids and gases. This valve is used for process, instrumentation, and power applications in a variety of industries.。Needle valves are used for precise regulations of liquids or gases in a piping system by moving the tip on the valve stem (the needle) into and out of the flow. Both the shape of the stem tip and the fine threads on the valve stem help the needle to be placed at precise points between fully open and fully closed. A needle valve's material type determines its usage—for example, metal valves are suitable for high pressure environments, while composite valves can be used in light weight applications The bonnet on needle valves can be integral (forged or milled as part of the valve body for strength), threaded (for durable pressure-tight seals where removal or replacement is not needed), or union (fits over the valve stem and held in place with a ring nut for repeated removal and replacement). Hand wheels, lever, and T-bar handles are made from various composites and materials that can be color coded for quick identification. These valves are used as either stand-alone valves or as flow control valves for gauges or instruments that could be damaged by flow and pressure fluctuations. Needle valves are suitable for use in fine adjustment and regulated flow applications in industries such as gas, chemical, hot water heating, and in scientific labs and textile manufacturing.。 Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems for fluid handling, filtration, sealing and shielding, climate control, process control, and aerospace applications. The company, founded in 1918, is headquartered in Cleveland, OH. 。 。 。 。
