HB802A-80 Series – High-Efficiency Vapor Recovery Vent Valve for Fuel Tanks

HB802A-80 Series – High-Efficiency Vapor Recovery Vent Valve for Fuel Tanks

The HB802A-80 vapor recovery vent valve is a crucial component designed for the top of petroleum and chemical tanker trucks, installed either on the manhole cover or directly on the tank roof. Its primary function is to regulate vapor flow into and out of the tank during loading and unloading operations, ensuring safe and efficient operation of the vapor recovery system while minimizing emissions. The outlet connects to the vapor recovery pipeline via a flexible rubber hose, allowing seamless integration with commercial fuel recovery networks.

Global Terminology Variations
This type of valve is known by various names across the world, reflecting local industry conventions:
Germany: “Dampfrückgewinnungs-Ventil für Tankdeckel”
France: “Soupape de ventilation pour récupération de vapeur”
Italy: “Valvola di sfiato per recupero vapori”
Spain: “Válvula de ventilación para recuperación de vapores”
Netherlands: “Dampterugwinningsventiel voor tankluik”
United Kingdom: “Vapor Recovery Tank Vent Valve”
Asia & South America: Commonly referred to as “Fuel Vapor Vent,” “Tank Top Recovery Valve,” or “Petrol Vapor Control Valve.”
Despite differences in terminology, the valve’s role remains the same: maintaining tank safety, controlling vapor emissions, and supporting efficient recovery of fuel vapors during transport.

Key Features
Durable Aluminum Construction: The valve body is die-cast aluminum with surface oxidation treatment, offering corrosion resistance and extended service life.
Stainless Steel Internals: Springs, shafts, and filter mesh components are made of 304 stainless steel to ensure smooth operation and longevity.
European Standard Compliance: Conforms to TTMA stud flange standards, compatible with global tanker systems.
Pneumatic Control: The valve operates with a control air pressure of 0.4–0.8 MPa, enabling precise vapor regulation.
Sealing and Safety: Buna-N gaskets provide excellent sealing performance under varied pressures, preventing leaks and protecting the environment.
Operational Range: Suitable for petrol vapor, with a working pressure of 0.6 MPa and temperature tolerance from -20°C to +70°C.
Flexible Connection: A flanged connection allows secure attachment to vapor recovery pipelines.

Applications
Fuel tanker trucks for petrol, diesel, and other light hydrocarbon liquids
Industrial chemical tanks requiring vapor recovery solutions
Systems designed to comply with environmental regulations on hydrocarbon emissions
Tankers integrated with on-site or mobile vapor recovery systems

The HB802A-80 series vent valve provides reliable vapor management, enhances safety during tank operations, and helps operators meet environmental standards globally. Its robust construction, precise pneumatic control, and compatibility with international flange standards make it a trusted choice for tanker operators in Europe, Asia, and South America.
