Specification
High Quality Water Oil Gas Manual Stainless Steel Forged Globe Valve
I. Product Overview
NEWWAY forged stainless steel globe valves feature A182 F304/F316 forged stainless steel bodies, compliant with ASME B16.34 standards for Class 600 (PN100) high-pressure applications. The lift-type disc enables flow cutoff and regulation, covering DN15-DN50 (1/2″-2″) with -20℃~425℃ temperature resistance for water, oil, and gas in high-pressure pipelines. Forged construction and dual sealing ensure reliable operation in petrochemical, power, and metallurgical industries.
