Double Door Wafer Check Valve
The Double Door Check Valve is a very short lay length valve- perfect for refineries, petrochemical plants, and pump stations. This wafer check valve 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.
