What Is An Oversized Valve?

Oversized valve refers to a valve with a very large nominal diameter, usually above DN1400mm. This valve is mainly used in large pipeline systems, such as pipeline systems in oil, gas, chemical and other industries.

Oversized valve is characterized by large diameter, complex structure, large weight, high sealing performance requirements. Due to its large diameter, the resistance drop and noise when the fluid passes through will be relatively large, so special attention needs to be paid to the design and manufacturing quality of the valve.

Common types of Oversized valves are butterfly valves, plate valves, flap valves and so on. These valves are usually structured in a two-way seal form to ensure the reliability and durability of the sealing performance. In addition, the oversized valve also needs to consider the influence of fluid temperature, pressure, corrosion and other factors, so the requirements for materials are also relatively high.

Oversized valves are usually used in the pipeline systems of large ships, such as oil tankers, liquefied gas carriers, bulk carriers, etc. Oversized valves are mainly used to control and regulate the flow and pressure of gas or liquid in large pipeline systems to ensure the normal operation and safety of ships.

On oil tankers, oversized valves are mainly used to control and regulate the transportation and storage of liquids such as fuel oil and lubricating oil to ensure the normal operation of oil tankers. In the liquefied gas transport ship, the Oversized valve is mainly used to control and adjust the loading, unloading and transportation process of liquefied gas to ensure the safety of the ship. On bulk carriers, Oversized valves are used to transport solid materials, such as coal and ore.

Oversized valves are usually made of high-strength materials, such as cast steel, stainless steel, etc., and have a large bearing capacity. These valves need to undergo rigorous inspection and testing to ensure their safe and reliable performance. On large ships, the maintenance and maintenance of oversized valves is also very important, and regular cleaning, lubrication and overhaul are needed to ensure their normal operation and extend their service life.
