Needle Valves
Needle Valves are specialized small-port valves equipped with a slender, finely threaded needle-shaped plunger that enables extremely precise flow rate regulation and isolation. Zeron Fasteners manufactures premium instrumentation Needle Valves engineered to handle extreme pressure differentials and critical gauge/sampling lines with zero leakage.
Our Needle Valves feature precision-machined non-rotating spindle tips to prevent galling and ensure extended seat life. Designed in forged body configurations with integral, screwed, or union bonnets, these valves are manufactured in Stainless Steel (304, 316, 316L, 321), High Nickel Alloys (Inconel 600/625, Monel 400, Hastelloy C276), and Duplex Steel, supporting operating pressures up to 10,000 PSI and 15,000 PSI.
