Stainless Steel 316 Needle Valve, DN6, PN320, 1/8 Inch, BW

Key Specifications / Features

The Stainless Steel SS 316 Needle Valve is designed for precise flow control in high-pressure applications. With a DN6 (1/8 inch) size and a PN320 (Class 2500 LB) pressure rating, it ensures reliable performance under demanding conditions. The valve features butt-weld ends for secure, leak-free installation and is operated using a handwheel for easy and accurate adjustments. Made from SS 316 stainless steel, it offers excellent corrosion resistance.

This valve is designed for both butt welding and external thread connections, offering multiple connection methods that simplify installation and disassembly. The tight connections ensure excellent sealing performance. Widely used in power plants, oil and chemical industries, and instrument measurement pipelines, the external thread needle valve provides reliable sealing and a long service life. In the event of sealing surface damage, only the vulnerable parts need to be replaced, allowing for continued use. During installation, ensure that the medium flow direction aligns with the arrow on the valve body.
