CVIII Double Disc Check Valves

Category:

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 contructed to meet and exceed AWWA C518.
