Bronze Lug‑Type Check Valve for Marine Seawater Pipeline, Lug Connection

Working Principle
Bronze Lug‑Type Check Valve works by the swing disc opening under medium pressure. When pipeline flow reverses, the disc closes automatically to block backflow. The lug‑type design enables end‑of‑line installation without counter flange, which greatly simplifies on‑site pipeline construction.
