Specification
DN15~DN600 PN16 Ductile Iron Resilient Seated Flange Gate Valve
I. Product Overview
NEWWAY resilient seated flange gate valve is a robust flow control solution engineered for water supply, industrial pipelines, and medium-pressure systems. Crafted with ductile iron, WCB carbon steel, or stainless steel (CF8M), it features a resilient seated design and flange connection to ensure reliable shut-off and flow regulation. Compliant with API 600, API 6D, and ANSI standards, it operates across -46℃~550℃ (depending on material) and handles water, oil, steam, and mild corrosive media. With a full-port design and outside screw & yoke (OS&Y) structure, it balances sealing performance, durability, and ease of maintenance—ideal for municipal water supply, petrochemical, and power generation industries where stable flow control is critical.
