Model L12-TH
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.
