Inland Tankers
Certified Pressure/Vacuum Valve and detonation arrester Solutions for River and Inland Waterway Vessels
Inland tankers operate under unique regulatory frameworks and challenging operational conditions. Restricted air draft, proximity to crew areas, frequent portcalls and ADN compliance requirements place specific demands on the vessel’s tank protection system.
At Pres-Vac Engineering, we deliver compact, high-performance pressure vacuum valves and venting solutions designed specifically for inland tankers transporting oil products, chemicals and hazardous liquids.
Operating Close to Crew and Infrastructure
Unlike ocean-going tankers, inland vessels operate:
- In confined waterways
- Close to populated areas
- With limited deck space and low air draft
- Under ADN regulatory requirements
- With frequent loading and discharge operations
This makes safe vapour handling and precise pressure regulation even more critical.
Our high velocity pressure vacuum valves are engineered to maintain stable tank pressure while ensuring safe gas dispersion – even in restricted height installations.

ADN and European Compliance
Inland tankers transporting hazardous liquids must comply with:
- ADN regulations
- ATEX requirements
- Relevant ISO standards for detonation and flame arresting and venting equipment
Our valves are certified for explosive atmospheres and tested according to ISO 16852 flame transmission requirements.
Full documentation and Type Approval Certificates ensure smooth approval processes with classification societies and authorities.
Safety in High-Traffic Areas
Inland tankers frequently operate near terminals, bridges and populated shorelines. Vapour dispersion must therefore be controlled and predictable.
Our high exit velocity valve design ensures:
- Safe vertical gas dispersion
- Reduced exposure risk for crew
- Lower risk of vapour accumulation on deck
- Compliance with emission control requirements
This is particularly important when transporting volatile oil products or chemicals with low flashpoints.
Built for Frequent Operations
Inland vessels typically perform more loading and discharge cycles
than deep-sea tankers.
Our pressure vacuum valves are designed for:
- Frequent opening cycles
- Minimal wear and tear
- Simple onboard maintenance
- Interchangeable pressure/vacuum units
Reduced mechanical complexity means fewer moving parts and longer service intervals – lowering total lifecycle cost.
