2.5" BSP Tank Container Safety Valves – Pressure & Vacuum Protection for Tank Containers

2.5" BSP Safety Valve for Tank Containers and Road Tankers

Our high-quality 2.5" BSP tank container safety valves provide reliable protection against both overpressure and vacuum conditions in tank containers and road tankers. These combined pressure and vacuum relief valves are specifically designed for applications where maximum safety, operational reliability, and compliance with international transport and safety standards are essential.

By combining pressure relief and vacuum protection in a single compact valve, your tank is effectively protected against harmful pressure fluctuations during transportation, loading, unloading, and storage.

Optimal Protection Against Overpressure and Vacuum

Pressure changes can occur during the transport and storage of liquids and chemicals. Excessive pressure can create hazardous situations, while vacuum formation may cause deformation or damage to the tank.

The combined 2.5" BSP pressure and vacuum safety valve responds precisely to preset pressure and vacuum settings. Excess pressure is safely released, while air is allowed to enter the tank when vacuum conditions occur. This ensures optimal protection of both the tank container and its valuable cargo.

Suitable for the Chemical Industry and ADR Transport

These pressure and vacuum safety valves are widely used in:

• Tank containers
• Road tankers
• Chemical processing plants
• ADR transport applications
• Storage and process tanks
• Installations handling aggressive or corrosive media

Thanks to their robust construction, these valves are designed to withstand demanding industrial environments and long-term operation.
