High Pressure Needle Valve SS 316 1/2" NPT (MXF) Steel Needle Valve
A needle valve is a type of valve with a small port and a threaded, needle-shaped plunger. 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 400 materials. Features of High Pressure Needle Valve (F x M) include :
1) One piece Sturdy Construction increases its pressure and temperature capacity. Increases life of the Needle Valve.
2) Panel Mounting Arrangement allows ease in mounting and minimizes vibration
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
Needle Valve Work:
Needle valves open and close an orifice with a tapered end that raises and lowers with the spin of a handle. Figure 2 shows a needle valve cross sectional view, design, and components. The handle (A) is connected to the plunger, also called a stem (F). When you turn the handle, the plunger moves up or down based on the threads (C). The locking nut (B) prevents it from fully unscrewing. As the plunger moves down, the tapered pointed end (I) comes into contact with the valve seat to fully seal the orifice (H). Often, the valve seat is also tapered. There are various options and sizes available to connect it to a pipe or hose through the port connection (G) on the input and output. The bonnet (D) is connected to the valve housing (E), which can be made out of different materials like brass or stainless steel.
Based on the threads, you can very precisely locate the plunger’s tapered end away from the valve seat to accurately control the flow rate. Therefore, by varying the plunger location you will control the flow rate between maximum and zero.
