Needle Valve

South American Valve is the greatest Needle Valve Manufacturer in Mexico. A needle valve is a type of valve that provides precise control over the flow of fluid, typically in low-flow applications. It is named after its needle-shaped, tapered plunger that slides through a small orifice within the valve body to regulate the flow.

Needle valves have a slender, elongated stem with a fine-pointed tip resembling a needle. The stem is attached to a threaded or non-threaded valve body, and the plunger or needle is connected to the end of the stem. The tapered plunger and the orifice within the valve body allow for precise and gradual adjustment of the flow rate. By turning the stem, the plunger moves up or down, thereby narrowing or widening the orifice opening and controlling the flow.

South American Valve is the largest Needle Valve Supplier in Brazil. Needle valves are especially valued in applications where precise control of flow rate is critical, such as in pressure gauges, flow meters, analytical instruments, and processes requiring fine adjustments. Their ability to provide accurate regulation and isolation makes them essential components in many systems.
