Needle valves are precision flow control devices designed for accurate throttling and on-off operation in piping systems. They feature a slender, needle-shaped plunger that fits into a matching seat, allowing fine adjustment of fluid flow rates. Compact and reliable, they are widely used in applications requiring precise flow control, especially for low-flow and high-pressure systems.
Simple yet robust structure, consisting of valve body, needle plunger, stem, bonnet and handle. The needle-shaped plunger ensures tight sealing and precise flow regulation, while the durable valve body (stainless steel, brass, carbon steel) offers corrosion and high-pressure resistance, adapting to harsh industrial environments.
Exceptional precision in flow throttling, capable of controlling even minimal fluid flow rates. Tight shut-off performance prevents leakage, and the manual handle allows fine-tune adjustment for optimal system operation. Suitable for high-pressure, low-flow applications, compatible with liquids, gases and steam.
Equipped with threaded connections for easy installation in small-diameter pipelines, ideal for laboratory equipment, instrumentation and residential gas systems.
Flanged connection design, suitable for large-diameter, high-pressure industrial pipelines, widely used in petrochemical, power generation and chemical processing industries.
Widely applied in petrochemical, power generation, aerospace, laboratory, pharmaceutical and HVAC industries. Suitable for flow control in instrumentation lines, pressure relief systems, gas pipelines and other scenarios requiring precise throttling and reliable shut-off.
