Energy Management Trim Technology

Avon, Mass.—Custom engineered for severe service application, V-LOG trim provides staged pressure reductions through a series of discrete flow channels combining 90° turns with intermediate expansions and contractions within the flow passage. Energy levels are efficiently managed and dissipated during the pressure reduction process, eliminating valve problems.
