Needle Valve

At its essence, a needle valve comprises a slender, tapered needle that fits into a conically shaped seat. This design allows for precise adjustment of the flow rate by controlling the opening through which the fluid passes. By rotating the valve stem, operators can finely adjust the position of the needle, thereby regulating the flow of fluid with exceptional accuracy.
