Low Fugitive Emission Valve
Selection Guide

As the EPA cracks down on the fugitive emissions released through valves, the need to implement low emission valves on both new and retrofit installations intensifies. At Assured Automation, we have answered this need by sourcing a complete range of low emission valves for our customers. This includes ball valves with emission containment packs and plug valves, butterfly valves, and gate valves with special low emission stem seals make up the offering. If you need help selecting a low emission valve for any application, call the experts at Assured Automation.
