New Emergency Relief Valve Delivers Superior Sealing and Industry-Leading High Flow Performance

Superior Sealing. Reduced Leakage. 10% Overpressure Protection.

Houston, TX, USA – LaMOT Valve & Arrestor, a global leader in pressure and vacuum relief solutions, has released the Models L22E & LV22E Emergency Relief Valves, engineered to deliver rapid overpressure protection with industry-leading sealing performance and exceptional flow rates.

L22E and LV22E Emergency Relief Valves

Designed for API 2000 / ISO 28300 compliance, the Models L22E (pre-configured) and LV22E (fully configurable) open fully at just 10% overpressure, venting large volumes during fire or upset conditions to help prevent tank rupture. Enhanced sealing technology limits fugitive emissions to no more than 1 SCFH at 90% of set pressure, supporting both safety and environmental goals.

“Operators are looking for more than just emergency protection — they want reliability, tighter sealing, and easy installation,” said Trey Rothenberger, Vice President of Global Sales & Marketing at LaMOT Valve & Arrestor. “The Models L22E and LV22E deliver all three, making it one of the most efficient and maintenance-friendly emergency vents on the market today.”
