Emergency cut-off valve is also known as the submarine valve installed at the bottom of tank storage, the main seal in the tank.When the pipeline or valve is broken accidentally, the tank body should be kept sealed to avoid liquid leakage in the tank and improve the safety and reliability of transportation.Using steel lining plastic technology, body inner lining F46 material, shell using cast steel and stainless steel material, by precision casting integral forming, simple structure, durable, easy maintenance.
1, material shell: mainly used cast steel and stainless steel, lined with F46, after precision casting integral molding, durable.
2, corrosion resistance: the surface after pickling and electrostatic spraying treatment, with good corrosion resistance and wear resistance.
3. High flow rate: reasonable structural design ensures large flow rate.
4. Emergency cutting: when the impact of external force is greater than 1000J, the cutting groove of the valve body will break,
and the sealing of the tank will be maintained to effectively prevent oil leakage.
