GY801-B3 Built-in Breather Valve

Product OverviewMaintaining a safe pressure balance inside the fuel tank is crucial for operational safety and equipment lifespan. That's why DESEINOR offers pressure-vacuum vents, designed to prevent dangerous pressure buildup or vacuum conditions during fuel loading, unloading, and transportation.This vent is engineered to stop fuel leakage when the tanker rolls over, and it features ADR-compliant performance. By reducing internal components by 45%, maintenance is simplified, making it faster and easier than with traditional models. A single 1.5-inch/12 hex nut installed at the bottom of the manhole cover lift valve enables it to withstand extreme shock, vibration, and impact conditions. In the event of a tanker overturn or other accidents, the valve automatically reverses and seals to prevent fuel leakage. This has consistently proven its reliability in practical operations, helping to protect lives, prevent accidents, and avoid costly fuel spills that could cause environmental harm.
