MECHANICALLY
OPERATED 90°
EMERGENCY VALVE
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.
