It allows precise regulation of flow,although it is generally only capable of relatively low flow rates. Available in stainless steel, carbon steel, brass and alloy 400materials. Features of High Pressure Needle Valve (F x M) include : 1) One piece Sturdy Construction increases its pressure andtemperature capacity. Increases life of the Needle Valve. 2) Panel Mounting Arrangement allows ease in mounting and minimizesvibration 3) Common Sizes like 1/4″ 3/8″ and 1/2″ is available in stock.Common connection thread is NPT. 4) MTC With trace-ability and Hydro test Certificate issued PART No.SIZEA1A2BCDFNV/MF/HP/011/8″3825557045FNV/MF/HP/021/4″3825557550FNV/MF/HP/033/8″4228608055FNV/MF/HP/041/2″4832658560Needle Valve Work: Needle valves open and close an orifice with a tapered end thatraises and lowers with the spin of a handle. Figure 2 shows aneedle valve cross sectional view, design, and components. Thehandle (A) is connected to the plunger, also called a stem (F).When you turn the handle, the plunger moves up or down based on thethreads (C). The locking nut (B) prevents it from fully unscrewing.As the plunger moves down, the tapered pointed end (I) comes intocontact with the valve seat to fully seal the orifice (H). Often,the valve seat is also tapered. There are various options and sizesavailable to connect it to a pipe or hose through the portconnection (G) on the input and output. The bonnet (D) is connectedto the valve housing (E), which can be made out of differentmaterials like brass or stainless steel. Based on the threads, you can very precisely locate the plunger’stapered end away from the valve seat to accurately control the flowrate. Therefore, by varying the plunger location you will controlthe flow rate between maximum and zero. Different types of needle valves:A manually operated threaded needle valve (described above) is themost common type of needle valve. However, two additional variantsare: motorized and angle. Motorized Needle Valve: These needle valves don’t have a handle formanual operation, but instead use an electric or pneumatic actuatorto connect to and turn the plunger. These can be remotelycontrolled, used in a closed loop system, and/or put on a timer toaccurately control the flow rate remotely.Angle Needle Valve: These needle valves turn the output from theinlet by 90 degrees instead of in-line. The same operation conceptapplies, but the 90-degree angle can allow for better systemintegration. Figure 3 shows an example of an angle needle valve.Needle valve selection: When selecting a needle valve, four main characteristics and/orapplication requirements need to be taken into account: material,pressure, size, and temperature. MaterialThe needle valve's housing material (Figure 2 callout E) isspecified according to the application. The most common valvehousing materials are brass and stainless steel due to their rangeof chemical resistance, however, there are also other materialsavailable for special applications. Needle Valve Applications: Most constant pressure pump governors have needle valves tominimize the effects of fluctuations in pump discharge pressure.Needle valves are also used in some components of automaticcombustion control systems where very precise flow regulation isnecessary.Needle Valve Body Designs One type of body design for a needle valve is the bar stock body.Bar stock bodies are common, and, in globe types, a ball swivelingin the stem provides the necessary rotation for seating withoutdamage. Needle valves are frequently used as metering valves. Meteringvalves are used for extremely fine flow control. The thin disk ororifice allows for linear flow characteristics. Therefore, thenumber of handwheel turns can be directly correlated to the amountof flow. A typical metering valve has a stem with 40 threads perinch. Needle valves generally use one of two styles of stem packing: anO-ring with TFE backing rings or a TFE packing cylinder. Needlevalves are often equipped with replaceable seats for ease ofmaintenance. .content_format table{border:1px solid #dedede; border-collapse:collapse;}.content_format td{ padding:3px; border: 1px solid #dcdcdc;}.content_format { line-height: 24px; word-wrap : break-word ;}.content_format p{ margin-bottom: 10px; margin-top: 2px; padding: 2px;} Product Tags: Duplex Steel Needle Valve 2500psi Steel Needle Valve SS316 Stainless Steel Needle Valve Female Connection Needle Valve Duplex Stainless Steel Needle Valves For Oil And Gas TOBO STEEL GROUP CHINA We are a manufacturer specializing in the production of valves, wehave advanced production technology and inspection equipment, toprevent defective products We can supplyStainless Steel Ball Valve,Stainless Steel Gate Valve,StainlessSteel Globe Valve,Flange Check Valve,Wafer Butterfly Valve,SteelNeedle Valve,Knife Gate Valve,Stainless Steel Y Strainer and so on.
