Maintaining 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.
The vent delivers an exhaust flow rate of 1,900 SCFH at 3 psig.
Under a vacuum of 1 psig, it provides a flow rate of 4,000 SCFH.
It can be installed directly into standard 10-inch manhole covers, allowing easy integration into existing systems.
The design is lightweight and durable, weighing only 14.4 ounces, making it suitable for rugged fuel transport environments.
Tool-free maintenance and cleaning simplify service operations and reduce downtime.
A built-in dust screen prevents foreign objects from entering the valve core, protecting internal components.
