Emergency Valves make product handling safer. These Emergency Valves have a shear groove that meets 49 CFR 178.345-8. The seat area of the valve is located inside the tank shell as required by DOT regulations.

This valve gives you the advantage of a faster flow rate while fitting a standard 4" TTMA sump. The high flow rate is established by a full opening throat area. Emergency Valves are available in 90 degree elbow type or straight type, 4" TTMA flanges or Victaulic™ outlet, and mechanical or air assisted.
