Valve is a direct-acting, spring loaded, diaphragm type relief valve. The valve may be installed in any position and will open and close within very close pressure limits. The Model 55L is normally held closed by the force of the compression spring above the diaphragm. When the controlling pressure applied

the set pressure. Pop-acting relief valves do not immediately open completely (to 100% lift). Sufficient overpressure is necessary to achieve full lift. ASME-certified relief valves are required to reach full rated capacity at 10% or less over-pressure. Relief valves are code-certified by the National Board of Boiler and Pressure Vessel Inspectors.

A pressure relief valve is a safety device designed to protect a pressurized vessel or system during an over- pressure event. An overpressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pres- sure or maximum allowable working pressure (MAWP).
