SS 316 Needle Valve

A SS 316 needle valve is a high-precision, linear-motion modulating valve featuring a body cast or forged from molybdenum-bearing 316 stainless steel (such as ASTM A182 F316 or A351 CF8M) and a finely threaded stem mated to a long, tapered needle-shaped plunger. When the handwheel is rotated, the threaded stem provides micro-incremental movement of the plunger into a matching small-diameter orifice seat, enabling exceptionally precise flow regulation and calibration of low-flow fluid lines. The Type 316 metallurgy delivers superior resistance to chloride pitting, stress corrosion cracking, and organic acids, making it an ideal choice for sanitary food and beverage processing, high-pressure hydraulic instrumentation panels, and chemical injection systems. Instrumentation engineers and process system contractors can achieve flawless micro-metered flow regulation and robust corrosion defense by importing certified SS 316 needle valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
