Outlet — Available with an internally <br />threaded, externally threaded or <br />union connection. <br />2. Thermal Relief Valve — to reduce <br />pressure build up due to thermal <br />expansion. <br />3. Secondary poppet in open position <br />by pumping pressure. <br />4. Secondary poppet normally in <br />closed position. <br />5. When properly installed, all IOR <br />and IORP valves break at the shear <br />groove causing the valve to close <br />and preventing further gasoline <br />spillage. <br />6. Main poppet normally held open by <br />linkage. <br />7. Main poppet in closed position. <br />8. Inlet available with or without <br />threads for use with double <br />containment. <br />
