Check Valves - Select
A double check valve and a dual check valve are both types of backflow prevention devices designed to protect potable water supplies from contamination.
A double check valve consists of two independent check valves assembled in a single unit. This configuration provides a significant level of redundancy. If one valve fails to close, the second valve acts as a backup, preventing backflow into the water supply. Double check valves are commonly used in systems where the risk of contamination is moderate and where space allows for their installation.
On the other hand, a dual check valve typically refers to a single valve unit with two internal check seats or discs. It operates similarly to a double check valve but in a more compact form. Dual check valves are often used in residential applications and provide a simpler solution for backflow prevention in low-risk scenarios.
Both devices require regular maintenance and testing to ensure they function correctly, protecting against potential water contamination.
