Bronze Check Valves
Bronze check valves are designed to allow fluid to flow in one direction while preventing reverse flow. Bronze check valves typically feature a disc or other mechanism that opens when fluid flows in the desired direction and closes to prevent backflow.
Overview
Material:
Bronze check valves are made primarily from bronze, a metal alloy composed primarily of copper and tin. Bronze is chosen for its corrosion resistance, durability, and suitability for use in various applications, including marine environments.
Types:
There are different types of bronze check valves, including swing check valves, lift check valves, and ball check valves. Each type operates slightly differently but serves the same basic function of preventing backflow.
