HBREV-I Series Vapor Recovery Vent Valve – Efficient Tank Top Vapor Management

HBREV-I Series Vapor Recovery Vent Valve – Efficient Tank Top Vapor Management

The HBREV-I Vapor Recovery Vent Valve is a critical tank top component designed for fuel tank trucks. Installed on the manhole cover, the valve head sits inside the tank while the tail connects to the vapor recovery pipeline. It regulates vapor during bottom loading and unloading and ensures safe venting during transport. By opening the valve during loading and closing side vent valves, vapor can be recovered efficiently. When closed during transit, the valve seals the tank, preventing spills and enhancing operational safety.

Global Terminology Variations
This type of tank top vent valve is known differently worldwide, reflecting regional terminology while maintaining the same core function:
Germany: “Vapor-Rückgewinnungsventil für Tankdeckel”
France: “Vanne de récupération de vapeur pour trappe de réservoir”
Italy: “Valvola di recupero del vapore per coperchio serbatoio”
Spain: “Válvula de recuperación de vapor para tapa de registro”
Netherlands: “Vaporterugwinventiel voor tankluik”
UK: “Vapor Recovery Vent Valve for Tank Manhole”
In Asia and South America, it is often referred to as “油气回收通气阀” or “安全油气排放阀”.

Key Features
High-Quality Materials: Main body made of cast aluminum alloy, with seals in fluorine rubber or nitrile rubber for chemical resistance.
