Civacon's MaxAir™II 5 x 4 Air Operated Emergency Valve is an optimal choice for petroleum applications. The MaxAir™II series valves are uniquely engineered with no moving parts in the flow path for a superior flow rate.

The VA1050 and VA2050 3 Emergency Valves are 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 and VA2050 are purposely designed for fuel oil, lube oil and heating oil delivery trucks.
