High-precision pressure relief for nearly any application.
Though small, this critical component deserves your undivided attention. Research, precaution and investment now will yield tremendous benefits in the future – when your operation is on the line.
With your safety and success in mind, our engineers developed simple, reliable valves that make the most of fewer parts – simplifying function, reducing buildup, increasing flow and allowing for easier maintenance.
If and when the time comes, count on our relief valves to perform.
The L2300A provides emergency relief capacity above what can be supplied by standard operating valves. Use it to protect tanks, piping and low-pressure vessels from internal pressure damage.

The LaMOT Valve and Arrestor Model L1221B Pressure/Vacuum Relief Valve is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the 1200 Series products retain toxic vapors, atmospheric contamination is minimized which helps to provide increased fire protection and safety.

The LaMOT Valve and Arrestor Model L1201B Pressure/Vacuum Relief Valve is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the L1200 Series products retain toxic vapors, atmospheric contamination is minimized which helps to provide increased fire protection and safety.

The LaMOT Valve and Arrestors Model L1300A is used when vacuum relief is the only requirement. Intake relief necessary under working conditions is achieved by a spring or weight loaded pallet. This feature reduces the possibility of tank damage due to an excessive vacuum condition. Valve size must be selected to perform required vacuum relief under operating and thermal conditions.

Weight Loaded Pressure Relief Valve
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.

The LaMOT Valve & Arrestor Model L12E PVRV design was created to exceed industry needs. Extensive research and development have produced a product that achieve both superior sealing performance and industry leading flow rates,while also allowing customers to reach required flow with a potentially smaller sized valve. The pressure vacuum relief valve is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. The Model L12E superior sealing valves are developed to minimize fugitive emissions while providing increased protection and safety to tank equipment and on-site personnel.

It's easy to buy cheap components from second-rate wholesalers, stamp a name on them and list them at a markup – and some companies do exactly that.
It's a lot tougher to design the product in-house, manufacture it in your own facility, then test and fine-tune to perfection before putting it on the market. But we do. Because we know your system relies on us – so we'll only put our name on products you can trust.
