- Product Description
Full Lug Butterfly Valve | Durable Design, Custom Sizing, Fast Global Delivery
When you need a full lug butterfly valve that combines rugged durability with precise engineering, look no further. Designed for heavy-duty industrial applications, our D343H series valves ensure leak-proof performance, compliance with global standards, and seamless integration with pumps, compressors, and motor systems. With customizable sizing (DN50–DN2000) and pressure ratings up to PN40, we deliver valves that eliminate installation mismatches and costly project delays.
Engineered for Heavy-Duty Industrial Applications
Our product features a robust design with bidirectional sealing, low-torque operation, and full lug flanges for secure pipeline connections. Made from ductile iron, stainless steel (SS304/316), or corrosion-resistant alloys, these valves withstand pressures up to 250 PSI and temperatures from -20°F to 400°F. Ideal for water treatment plants, oil/gas pipelines, and HVAC systems, they’re built to last 10+ years in harsh environments.
