The LaMOT Valve & Arrestor Model L12F PVRV design was created to exceed industry needs. Extensive research and development have produced a product that achieve both superior sealing performance and industry leading flow rates, while also allowing customers to reach required flow with a potentially smaller sized valve. The 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. The Model L12F is superior sealing valves developed to minimize fugitive emissions while providing increased protection and safety to tank equipment and on-site personnel.
• Precision machining and manufacturing to accomplish superior sealing, aiding in
the reduction of fugitive emissions
• Ultra-tight sealing reduces product leakage and fugitive emissions
• Achieve various pressure setting by adding calibrated weights
• Industry leading flow rates
• Higher flow capacity to protect from both excessive pressure and excessive vacuum build up
• Peripheral and central seat guides ensure reliable, repeatable performance
• PPS pallet material is more corrosion resistant than other pallet materials and has
anti-freeze non-stick properties to aid in applications with potential pallet to seat freezing
• Designed for easy maintenance, thus reducing downtime and operational cost
• Size: 2” through 6”
• Casting Material: Aluminum
• Pallet Material: PPS (Polyphenylene Sulfide)
• Diaphragm Materials: Buna-N, Blue FKM or FEP
• Calibrated Weight Material: Zinc-Plated Steel or Stainless Steel
• Bolting Class: 150# ASME
• Available Pressure Settings: 0.5 osig to 24 osig (in 0.5 osig Increments)
• Available Vacuum Settings: 0.4 osig, 0.5 osig to 24 osig (in 0.5 osig increments)
• Leak Rate is compliant with API 2000
• Corrosion resistance can be enhanced with FKM soft goods
