Description

3-Piece Welded End Ball Valve – NSW

The NSW 3-Piece Welded End Ball Valve is engineered for reliable shut-off and flow control across a wide range of industrial applications. Designed to API 6D and ASME B16.34 standards, it supports pressure classes from 150 up to 2500 and is suitable for use with aggressive media including steam, oil, mud, water, and corrosive fluids. This valve features a blowout-proof stem, low torque operation, and a fully welded body construction for increased strength and zero leakage. The valve’s self-cleaning sealing surface, pressure balance hole, and top-entry design enable easy maintenance and extended service life. Made from high-grade cast or forged materials such as CF8M, WCB, Monel, Inconel, and Duplex Stainless Steel, this valve offers robust performance in demanding fluid handling systems. Available with RF, FF, or RTJ flange ends.
