The Cla-Val Model 55L (UL Listed, FM approved)Pressure Relief 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.

the pressure relief valve, therefore, is the process fluid. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure relief valve may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that

The available pressure ranges for this valve are from 4,5 to 70 bar (65 to 1000 psi), from 4,5 to 140 bar (65 to 2000 psi), and from 4,5 to 210 bar (65 to 3000 psi). Therefore, the main system

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).

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.

Relief valve Automatic pressure-relieving device actuated by the static pressure upstream of the valve. The valve opens in proportion to the increase in pressure over the opening pressure. It is primarily used for liquid service. Safety-relief valve Automatic pressure relieving device actuated by the static pressure upstream the valve.

This technical bulletin is dedicated to those pressure relieving devices which fall within the definition of direct-loaded safety valves, produced by PARCOL 

a pressure no less than 85% of their rating and UL requires oPeNING at a pressure no greater than 105% of their rating. Both standards require the relief valves to CLoSe within a percentage below oPeN. Choose the relief valve comparing static pressure to 90% of the relief valve's rating to determine the estimated minimum oPeNING
