Government & Military
The United States Military has been a customer of our 4100 series EV-O-Seal for various orders. Tooele Army Depot installed various sizes including from Ø24" up to Ø48" in their base for flue gas exhaust. The bubble tight shut-off was a must have in their current application. Our 4100 series features a double disc for redundant bubble tight (optional) shut-off in the event of a seal being damaged, airfoil reinforced disc (optional), an easy replacement of seal on sizes Ø48″ and larger without removing the valve from the line and a positive system isolation in positive or negative pressure systems.
