3” Air Operated Internal Valves

The VA1050 3" Emergency Valve is specifically engineered to allow greater flexibility of tank truck design and assembly. The internal air operation cylinder allows maximum utilization of under tank chassis space while the ”bellowed body” profile allows higher flow rates when unloading, and lower pressure drop when at the loading rack.
The VA1050 is purposely designed for fuel oil, lube oil and heating oil delivery trucks.
