UNOX Stainless Steel Needle Valve

UNOX Stainless Steel Needle Valve

The UNOX Stainless Steel Needle Valve is a precision-engineered valve designed to provide accurate and reliable flow control in demanding industrial applications. Built entirely from AISI 304 or AISI 316 stainless steel, it offers superior corrosion resistance and mechanical strength, ensuring long service life even in harsh environments such as chemical processing, oil and gas, power generation, and marine systems.

The fine-threaded stem and tapered needle design enable precise adjustment of flow rates, making this valve ideal for metering liquids, steam, or gases where exact regulation is critical. A metal-to-metal seating surface ensures tight shut-off and repeatable control, while the blow-out proof stem design adds an extra layer of operational safety.

The UNOX Stainless Steel Needle Valve is suitable for working pressures up to PN250 (≈ 3625 psi) and operating temperatures up to 400 °C (≈ 752 °F), depending on gasket selection. Compact in size, it can be installed in tight spaces and is available with a variety of end connections such as BSP, NPT, or compression fittings to meet different system requirements.
