Bottom Valve
The bottom valve, also known as the emergency shut-off valve, is installed at the base of a tank. It features a built-in shut-off groove that allows the valve body to disconnect along the groove when triggered, effectively sealing the tank's outlet in case of an accident to prevent leaks and ensure safe transportation.
The aluminum body undergoes oxidation treatment, offering both aesthetic appeal and strong corrosion resistance. The valve includes a high-quality stainless steel filter and ensures a high flow rate. In the event of blockage due to air pressure, it can be manually opened for quick access.
Designed with ease of maintenance, durability, and high performance in mind, this valve is ideal for oil companies and petroleum transporters who need a reliable, high-flow emergency solution.
