Stainless steel manual needle valve 

Needle valve is a common control valve, which Universal valve is particularly suitable for applications that require high-precision flow control and situations with limited space. The structure of a needle valve is similar to a sharp needle, with a small hole at the bottom for controlling flow. When the needle screw is rotated, the flow rate of the needle valve can be changed. Needle valves are generally composed of components such as valve bodies, valve cores, sealing washers, sealing gaskets, and handles. Among them, the valve core is the core component of the needle valve, which controls the flow rate through the rotation of the handle. The sealing gasket and sealing gasket are used to ensure the sealing performance of the needle valve. Needle valve has the following advantages: firstly, it can provide high-precision flow control function, suitable for places that require strict flow control. Secondly, needle valves have a compact structure and small volume, making them suitable f…
