Model L13T

Weight Loaded Vacuum Relief Valve – Top Mount

The LaMOT Valve & Arrestor L13T weight loaded vacuum relief valve (top mount) is designed for applications where additional vacuum relief is necessary. Intake relief necessary under working conditions is achieved by a weight loaded pallet. The L13T helps to provide increased fire protection and safety. Valve size must be selected to perform required vacuum relief under operating and thermal conditions.

  • Product leakage and fugitive emissions are reduced via ultra-tight sealing
  • Higher flow capacity to protect from excessive vacuum build up
  • Peripheral and central seat guides ensure reliable, repeatable performance
  • Designed for easy maintenance, thus reducing downtime and operational cost
