Maintaining safe pressure balance inside fuel tanks is essential for both operational safety and equipment longevity. That’s why DESEINOR offers a pressure vacuum vent designed to prevent dangerous pressure buildup or vacuum conditions during fuel loading, unloading, and transit movement.
Engineered to stop fuel spillage in the event of a tanker rollover and with ADR-compliant performance, this vent simplifies maintenance by reducing internal components by 45% making maintenance faster and easier compared to conventional models. A single 1.5"/12 hex nut mounted at the base of the manhole lift valve allows it to endure extreme shock, vibration, and impact conditions. In the event of a tanker rollover or other accident, the valve automatically seals in reverse to prevent fuel leakage. This has consistently demonstrated its reliability in real-world operations, helping to safeguard lives, prevent accidents, and avoid costly fuel spills that could result environmental hazards.
- 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.
