CW-12MW Hastelloy C276 flanged ball valve with lever PN16

Product Overview

The CW-12MW Hastelloy C276 Flanged Ball Valve is a premium, lever-operated quarter-turn valve engineered for ultra-aggressive chemical environments. Cast from CW-12MW (the casting equivalent of Hastelloy C276), it provides unmatched resistance to severe pitting, crevice corrosion, and strong oxidizers like ferric chloride, nitric acid, and wet chlorine gas.

Featuring a standard PN16 raised-face flanged connection and an ergonomic manual lever, this full-bore valve delivers bubble-tight bi-directional sealing and minimal pressure drop. It is the definitive choice for long-term mechanical reliability and strict environmental safety in petrochemical processing, pharmaceutical synthesis, and offshore marine operations.
