The emergency shut-off valve (also known as submarine valve) is installed at the bottom of tank trucks. When subjected to strong collision, the valve body breaks at the flange, separating the tank body from the pipeline while maintaining a sealed container - preventing liquid leakage and significantly improving transportation safety. Complies with GB/T932-2018 standard.
The valve body is constructed from lightweight aluminum alloy using low-pressure casting for superior strength and durability. The breakaway design ensures the tank remains sealed during accidents, effectively preventing fuel leaks.
