The PermaSeal Insertion Valve is a true resilient wedge gate valve developed with “clean seat” technology and offers reliable and repeatable watertight shutoff suitable for utilities’ exercise programs. Standard and oversized variants are now available in 4, 6, 8, 10, and 12 inches, and can be inserted into an existing water main with minimal service disruption. The valve meets AWWA industry standards and is compatible with most major pipe types.
