HB802L-80 Vapor Recovery Vent Valve – Advanced Vapor Management for Tank Trucks

HB802L-80 Vapor Recovery Vent Valve – Advanced Vapor Management for Tank Trucks

The HB802L-80 Vapor Recovery Vent Valve is a high-performance safety component designed for top-mounted installation on fuel tank truck manhole covers. It plays a critical role in controlling vapor during tank loading, unloading, and transportation, ensuring both operational efficiency and environmental safety.

This valve connects the internal tank space to the vapor recovery system via a hose or pipeline, allowing controlled vapor intake and release. During bottom loading or unloading, the valve opens to recover vapor while closing side plate vent valves, minimizing emissions. When the tanker is in transit, the valve remains closed, effectively sealing the tank and preventing leaks in emergency scenarios.

Global Names & Industry Recognition
Across the world, the HB802L-80 and similar vapor recovery vent valves are known by various local terms:
Germany: “Vapor-Ablassventil für Tankdeckel” or “Tankdampfventil”
France: “Vanne de récupération de vapeur pour trappe de réservoir”
Italy: “Valvola di ventilazione per vapore del serbatoio”
Spain: “Válvula de ventilación para vapor de tanque”
Norway/Sweden: “Tankluke dampkontrollventil”
UK/English markets: “Vapor Recovery Vent Valve for Tank Manhole.”
Asia & South America: “油气回收通气阀,” “安全油气排放阀,” “压力平衡油气阀”

Despite these different names, all refer to the same essential function: managing vapor flow, maintaining tank pressure, and preventing oil and vapor leaks during transportation.
