Model L11F

Weight Loaded Pressure Relief Valve

LaMot Valve & Arrestor Model L11F is designed for emergency relief capacity above that supplied by a standard operating valve used on tanks, piping, and low-pressure vessels. Pressure relief valves provide relief from excessive internal pressure which may cause tank damage. Calibrated weights are available for various setting.

Superior Sealing Performance

• Precision machining and manufacturing to accomplish superior sealing

• Ultra-tight sealing reduces product leakage and fugitive emissions

Industry Leading Flow Rates

• Higher flow capacity to protect from excessive pressure build up

• Optimal flow is achieve by a flow path with minimal obstructions from the tank

nozzle to the atmosphere

• Higher flow rates also allow these valves to be used in a wider range of applications

than valves with lower flow rates

• 100% overpressure technology

Direct Replacement & Easy Maintenance

• Direct replacement for any standard 150# ASME pressure relief valve

• Designed for easy maintenance, thus reducing downtime and lowering operational costs

• Fully field replaceable pallet assemblies

• Replacement pressure diaphragms “soft goods”
