Safety valve definition

Safety valve means a spring-loaded device which is activated automatically by pressure the purpose of which is to protect the tank against unacceptable excess internal pressure;
Safety valve means an automatic, pressure-relieving device actuated by the static pressure upstream of the valve and characterized by full opening pop action. The safety valve is used for gas or vapor service.
Safety valve means an automatic pressure-relieving device activated by static pressure upstream of the valve and characterized by full-opening pop action. It is used for steam, gas, or vapor service.
