These downloadable documents are in the Adobe Acrobat PDF format.

	Excess flow check valves are intended to close upon excessive discharge of vapor or liquid resulting from a break in the hose or piping system. They are used to protect cylinder, tank, and piping systems, and valves are available in a large variety of sizes and body configurations. When flow exceeds the valves setting, the valve closed and remains closed until the system equalizes. A built-in equalizing passage automatically opens the valve once pressure on both sides of the poppet are equal. Valves larger than 1/2-inch NPT have a drill size no. 60. Valves 1/2-inch and larger have a limited bypass to comply with NFPA 58.
