VST expands product offering with UL Listed 2583 Pressure Vent Valves

At NACS Show 2022, VST introduced the newest innovative product targeted at reducing fugitive emissions at gasoline dispensing facilities – UL Listed 2583 Pressure Vent (P/V) Valves.

The VST SENTRY™ P/V Valves are highly engineered products designed to protect the structural integrity of the Underground Storage Tank (UST) from extreme positive and negative pressure conditions caused by fuel drops and vehicle refueling events. These robustly, unique P/V valves are the latest addition to our product offering aimed at preventing unwanted vapor emissions from escaping into the environment.

VST offers two styles of the SENTRY™ P/V valve.

VST-PV-100 is a top-mount model that can be installed near the top of the vent pipe. It can be used as a quick and easy replacement for any traditionally installed P/V Valve.

Every SENTRY™ P/V valve is shipped with a specific style protective rain cap to keep out water and foreign debris.

Stainless steel TIP stinger
Testing hose
Bell adapter for connection to P/V test unit (P/V test unit not included)
