Valve-Ex Flo 1-1/4Mptx1-1/4Fpt 42Gpm Stl

These UL listed excess flow valves are intended for use in liquid or vapor systems. They can be used for filling, withdrawal and vapor equalization in containers or line applications, specifically long lines or branch piping. They are designed to protect against excessive discharge as a result of a break. The excess flow feature is designed to remain closed after activation until the system pressure equalizes on both sides of the shutoff poppet. WARNING: An excess flow valve will not activate if there is a break or leak downstream of the valve that does not equal or exceed the closing flow of the valve or if the excess flow valve installed exceeds the flow capacity of the system.
