Cryogenic ball valves with extended bonnets suitable for operating at temperatures as low as -196°C are specially designed to handle the extreme conditions of cryogenic applications. These valves are commonly used in industries such as LNG (liquefied natural gas) processing, industrial gas production, and other cryogenic fluid handling applications.Key features of cryogenic ball valves with extended bonnets for -196°C include:Low-Temperature Materials: The valves are typically constructed from specialized materials such as stainless steel, carbon steel, or other alloys with low-temperature properties to ensure performance and integrity in cryogenic environments.Extended Bonnet Design: The extended bonnet provides additional insulation and protection for the valve stem and packing to maintain proper functioning at extremely low temperatures.Sealing and Packing: The valve's sealing components and packing are specifically designed to remain effective and flexible at cryogenic temperatures, enabling tight shut-off and preventing leakage.Testing and Compliance: These valves undergo rigorous testing to ensure performance and compliance with industry standards for cryogenic service.Operational Safety: Cryogenic ball valves with extended bonnets are crucial for maintaining safe and reliable control of cryogenic fluid flows, contributing to operational safety in cryogenic systems.When selecting cryogenic ball valves for -196°C applications, it's important to consider factors such as material compatibility, pressure and temperature ratings, and compliance with relevant industry standards and regulations.
API 6D trunnion ball valve is a ball valve product that meets the requirements of American Petroleum Institute standard API 6D. This standard stipulates the design, material, manufacturing, inspection, installation and maintenance requirements of API 6D trunnion ball valves to ensure the quality and reliability of ball valves, and is suitable for various industrial fields such as oil and gas. Features of API 6D trunnion ball valve include:
1.The full bore ball is used to reduce the pressure drop of the valve and improve the flow capacity.
2.The valve adopts a two-way sealing structure with good sealing performance.
3.The valve is easy to operate and smooth, and the handle is marked for easy identification by the operator.
4.The valve seat and sealing ring are made of high-temperature, high-pressure and corrosion-resistant materials, which are suitable for various fluid media.
5. The parts of the ball valve are well separable, easy to install and maintain. API 6D trunnion ball valves are suitable for occasions in the industrial field that need to control fluid flow, cut off fluid, and maintain pressure stability, such as fluid piping systems in petroleum, chemical, natural gas, water treatment and other fields.
