Model L11E

Weight Loaded Pressure Relief Valve

The LaMot Valve & Arrestor Model L11E weight loaded pressure relief valve is designed to be used in applications where additional relief is necessary. It can be used in conjunction for emergency relief but that is not why it was designed. Pressure relief valves provide relief from excessive internal pressure which may cause tank damage. Calibrated weights are available for various setting.
