About Needle Valve
A needle valve is a small valve that controls the flow of liquid or gas in a system. It is perfect for high pressure and low flow setup because it permits precise adjustment. The flow is controlled by turning a stem connected to a tapered plunger which fits into a seat. These valves are often used in setups with pressure instruments for isolation and venting. Brass or stainless steel are used to make the majority of needle valves. Tesco Steel & Engineering is a manufacturer of needle valves known for producing long lasting, high quality goods that satisfy a range of industrial requirements. Our valves come in a variety of sizes and designs, making them appropriate for use in labs and plant operations alike.
Needle valves come in different types manual needle valve, inline needle valve, angle needle valve, and mini needle valve. A basic manual valve includes a handle connected to a stem that threads into the valve body. As the handle turns, the tapered plunger moves up or down, opening or closing the flow. The valve body can be brass or stainless steel, and the connections vary threaded, welded, or flanged. A locking nut prevents over-rotation, while the bonnet holds all parts in place. Each design offers precise control, a tight seal, and flexibility for different systems.
