Double Disc Check Valves

VSI Waterworks Double Disc Check Valve

VSI Waterworks’ Series CVIII Disc Check Valves

The VSI Waterworks’ CVIII Check Valve is a very short lay length valve- perfect for refineries, petrochecemical plants, and pump stations.

The dual door design relies on a variable number of springs to adjust to the desired opening pressure range. The spring loaded design combined with the resilient seat produces a very fast non-slam closure.

Valves in this line are designed and constructed to meet and exceed AWWA C518.
