Durable Open Atmospheric Vent Valve for Fuel Storage Tanks

Durable Open Atmospheric Vent Valve for Fuel Storage Tanks

Maintaining proper airflow in fuel storage tanks is essential for operational safety and long-term tank integrity. The HBOAV-XX Series Open Atmospheric Vent Valve is designed to provide a simple, reliable solution for venting underground and above-ground fuel tanks. These vents allow tanks to equalize pressure naturally with the atmosphere, preventing structural stress, vapor buildup, and potential safety hazards.

This type of valve is known by various names around the world. In North America and Europe, it is often called Open Vent Valve, Tank Breather Cap, or Atmospheric Relief Vent. In Asia and the Middle East, industry professionals may refer to it as a Fuel Tank Vent Cap, Oil Storage Atmospheric Vent, or Tank Breathing Device. Despite regional terminology differences, all serve the same purpose—ensuring continuous airflow and preventing debris, water, or insects from entering the tank vent line.

The HBOAV-XX Series is typically installed at the top of vent pipes, around 4.5 meters above the tank, to optimize airflow and maintain consistent tank pressure balance. The valve is constructed with a robust aluminum body and cap, and incorporates a 40-mesh brass screen to protect against contaminants. Its always-open design allows the tank to vent freely, eliminating the need for complex mechanical pressure controls.

Available connection options include 1.5-inch and 2-inch female NPT or BSP threads, with flanged options available upon request to meet specific project or regional requirements. The simple yet durable design ensures minimal maintenance while providing reliable performance in a variety of environmental conditions.

The HBOAV-XX Series is particularly well-suited for:
Portable and stationary fueling stations
Underground and above-ground oil storage tanks
Industrial or commercial fuel depots

By combining simplicity, durability, and protective features, the HBOAV-XX Open Atmospheric Vent Valve provides an effective, low-maintenance solution to maintain tank safety, reduce contamination risks, and ensure consistent tank operation across global markets.
