Betts Emergency Valves
A Betts valve is a fixture designed to allow personnel to unload an overturned tank truck through a capped three-inch NPT cleanout without spillage of the product. These emergency valves permit the removal of the liquid through the cleanout cap and product discharge through proper hoses to the level of the cleanout cap. ES&H maintains these units on our hazmat response trailers. These are very useful in the event of a chemical tanker overturning when drilling the tank is not a viable option due to tank composition, position or preference.
