What is a shear valve also known as?

A shear valve is also commonly referred to as a crash valve. This type of valve is specifically designed to prevent the release of fluids in the event of a sudden impact or collision, which is particularly important for underground storage tanks (USTs). When a shear valve is installed, it is positioned above the tank and is designed to shut off and seal the flow if the piping is subjected to a shear force, such as during a vehicular accident.

The function of the crash valve is crucial in minimizing the risk of leaks and potential environmental contamination, as it helps contain any fluid that could otherwise escape from the tank during an emergency situation. This safety feature is part of the regulatory requirements for USTs to protect both human health and the environment.

Choosing the correct terminology is essential for understanding the operational and safety mechanisms in place for hazardous materials management, which enhances the overall safety of public and private spaces.
