Resilient Seated Gate Valves (GVI)

The VSI Waterworks’ GVI Gate Valve was designed to be a versatile flow isolation valve for line sizes of 2″ to 72″.

The gate is fully encapsulated with resilient material to match the line media’s properties, producing a robust valve.  The body features a full free open passageway equal to the nominal line size to minimize pumping losses.  The simple two moving component construction practically eliminates inadvertent damage.

Valves in this line are designed and constructed to meet and exceed both AWWA C509 and AWWA C515.
