Triple eccentric butterfly valve selection butterfly valve is one of the commonly used valves on the pipeline of industrial equipment, also known as high pressure butterfly valve, widely used in petrochemical, gas production, water treatment and other industrial fields. Due to the advantages of simple structure and small size, the hard seal three eccentric disc butterfly valve is widely used in chemical installations to regulate the flow or cut off the medium in the pipeline.

Triple eccentric butterfly valves for oil applications

The oil and gas industry faces the unique challenge of operating in harsh conditions. The oil rigs and wells have extreme temperatures greater than 816 degrees and pressure more than 25k psig. The operating conditions can sometimes be cryogenic, with temperatures below -162 degrees. Valves used in the gas and oil fields need to perform well throughout the operation of a well’s life. It needs to regulate upstream, downstream and midstream operations.

Upstream – Valves are used to control the upstream flow of natural gas and crude oil.

Downstream – Includes crude oil refinement and delivery of petrol products. Here, the valves should handle high temperature and pressure found in refineries.

Midstream – Include storage and transfer of gas and oil from remote locations using long pipes fitted with valves to regulate flow and protect the equipment.

Advantages of using a triple eccentric butterfly valve

• Triple offset butterfly valves have a crucial advantage: they seal metal-on–metal without friction. They are also more resistant to temperature changes, so they last longer.
• Triple offset butterfly valves have a much lower risk of leakage than other valves.
• They have a very tight seal, which is ideal for applications requiring a high degree of sealing.
• They are available in various sizes and specifications, making them suitable for a wide range of applications.
