GY801-80M Fuel tanker Bottom Valve

The **stainless steel bottom valve** under DESEINOR products is a core safety component installed at the bottom of chemical tank trucks, tank containers and oil tankers, which ensures safe and efficient discharge of media.

This emergency shut-off valve is specially designed for **chemical corrosive liquid** applications, featuring excellent flow capacity and fast response performance in emergency scenarios.

This series of high-performance stainless steel bottom valves supports two actuation modes: **external exhaust control** and **manual cable release**, enabling flexible adaptation to various on-site operation requirements. The product is compatible with a wide range of media including corrosive liquids, low-temperature gases, biodiesel, gasoline, ethanol and methanol. Equipped with chemical-resistant seals, it effectively enhances the product's media compatibility and durability.

Safety and Compliance

This bottom valve is built-in with a shear groove structure, whose design and testing fully comply with the standards of **U.S. Federal Regulation 49CFR178.345-8** and the **Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)**.

In the event of a vehicle collision, the valve body will separate along the shear groove while maintaining a tight seal with the tank flange, preventing medium leakage and protecting the integrity of the valve mechanism inside the tank.

 Operating Pressure

- For crude oil applications, the valve opens at a minimum line pressure of **70 psi (4.83 bar)** to counteract a tank pressure of 35 psi (2.41 bar).

- For refined petroleum applications, the valve requires a minimum line pressure of **30 psi (2.06 bar)**.

This stainless steel bottom valve also complies with the requirements of **API 1004 (American Petroleum Institute Standard)** and **EN 13083 (European Standard)
