The main body of the subsea valve is made of lightweight aluminum alloy, which is durable and reasonably designed, with good anti-corrosion and wear resistance. As one of oil tank truck parts, subsea valves are usually installed in the bottom flange connection of oil tanker trucks, and the sealing mechanism is deep inside the tank, which is in the closed state when not loading and unloading. Using stainless steel spring pressure for axial self-sealing, so that the submarine valve is in a normally closed state, through the transmission mechanism for opening and closing operations. The shell is equipped with a cut-off groove, which can effectively absorb the energy transferred by the impact of the vehicle to destroy the pipeline. In the event of an accident with the tanker, the subsea valve body breaks from the cut-off slot because the cut-off slot can’t withstand the excessive impulse, separating the tank from the pipeline, thus ensuring the integrity of the sealing mechanism, avoiding the leakage of oil, improving the safety of transportation and preventing the pollution of the environment. With the refined design, high flow rate and high drop are realized in the liquid flow channel to ensure the maximum benefit. Reliability of triple sealing on the piston and reduced maintenance. Castings are carefully designed to reduce weight and improve flow.
Features:
- Constructed with aluminum alloy low-pressure casting for durability.
- The surface is anodized for better oxidation resistance and abrasion resistance.
- Reasonable structural design ensures large flow through.
- When subjected to strong collision, the valve body breaks at the cut-off groove and ensures the sealing of the tank, effectively preventing oil leakage
- Used in multi-compartment tanker, can carry out separate loading and unloading of different oil compartments
- Conforms to EN13083 requirements, flange TTMA standard.
