Aluminum Alloy Pneumatic Submarine Emergency Shut-off Valve
Emergency cut-off valve,also named subsea valve,is installed at the bottom of the tanker,and the valve is sealed in the tank.There is no cut-off groove on the valve body.When the tank body is subjected to a strong collision,the valve body will break at the flange.The tank body is separated from the undercarriage pipeline to become an independent sealed tank body.It can prevent liquid from leaking out and greatly improve the safety of transportation.It is a pipe fitting part for the tanker trucks carrying light fuel oil.It cannot be installed in the liquid with strong corrosiveness.This product meets the relevant requirements of the GB/T 932-2018 standard.
Feature:
1.The main material is light weight aluminum alloy,which is integrally formed by low-pressure casting,which is light,strong and durable.
2.The surface of the product is oxidized and has good corrosion resistance and wear resistance.Reasonable structure design to ensure large flow through.
3.When the bottom of the tanker is hit,the emergency cut-off groove automatically breaks to separate the tank from the bottom and become an independent closed tank to prevent liquid leakage.
