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.

Round Pan Thief Hatch
The LaMOT Valve & Arrestor Model L12-TH Thief Hatch incorporates a spring loaded pressure/vacuum relief valve within the device. Thief Hatches are used on steel or fiberglass (FRP) low pressure storage tanks. The hatch has a gauging hook integrated to the base to be used while sampling the tank, providing access for level gauging, sampling, and overpressure/vacuum protection for the tanks, all in one compact design. Superior sealing is achieved from an active envelope pressure gasket that expands around the base to increase seal until the designated pressure setting is reached. This design saves you money by greatly reducing vapor loss compared to a traditional thief hatch design.View Round Pan Thief Hatch chevron_right
Long Pan Thief Hatch
The L12-TL incorporates a large working surface, larger cover, and a gauging and sampling hook into the base. The base is inclined to match the slope of the API12 tank’s roof to provide a level working surface. A bonding strap and SLIC™ pins come standard with the L12-TL.View Long Pan Thief Hatch chevron_right
