Model L1201B

Pressure/Vacuum Relief Valve

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.
