L&J Technologies 94020 Conservation Vent (Pressure & Vacuum)

The L&J Technologies 94020 Pressure & Vacuum Vent is a conservation vent used to help manage normal pressure and vacuum conditions in storage tank venting applications.

Designed for installation on tank systems that require both pressure relief and vacuum relief capability, the 94020 supports controlled venting as part of a broader tank protection equipment strategy.

The 94020 pressure and vacuum vent is used where conservation venting is needed to help relieve pressure buildup and admit air or vapor as vacuum conditions develop during routine tank operation.

This makes the vent suitable for applications involving filling, emptying, thermal changes, and other operating conditions that can create pressure or vacuum movement within a tank system.

Available in open vent and closed vent configurations, the L&J 94020 can be selected based on the venting arrangement, piping requirements, and application needs.

Construction options may include aluminum, stainless steel, carbon steel, cast iron, or ductile iron body configurations depending on product selection and project requirements. The vent design also supports service access and available accessories such as visual indicators and pressure or vacuum limit switch options.

For industrial facilities evaluating conservation vents, pressure/vacuum vents, or related tank venting equipment, Process Controls Corporation can help identify the appropriate L&J Technologies 94020 configuration based on the application, installation requirements, and supporting system specifications.
