Aluminum Alloy Pneumatic Emergency Shut-off Valve for Tank Trucks -20- 70 Design Tempreture and Positive Pressure 0-0.6Mpa

This emergency cut-off valve (also known as subsea valve) is installed at the bottom of tanker trucks. The valve remains sealed within the tank and features no cut-off groove on the valve body. In case of strong collision, the valve body breaks at the flange, separating the tank body from the undercarriage pipeline to create an independent sealed unit. This design prevents liquid leakage and significantly improves transportation safety.

This product is designed for bottom loading/unloading of tanker trucks carrying light fuel oil. Not suitable for highly corrosive liquids. Complies with GB/T932-2018 standard requirements.

1. Lightweight aluminum alloy main body, integrally formed by low-pressure casting for strength and durability
2. Hydraulic transmission control ensures smooth, safe and reliable operation
3. Oxidized surface provides excellent corrosion and wear resistance with optimized structure for high flow capacity
4. Automatic emergency cut-off system separates tank from undercarriage upon impact to prevent liquid leakage
