The power station swing check valve is mainly suitable for the pipelines of the various systems of thermal power station to prevent the medium from flowing. Compared with other valve products, the power station swing check valve-outbound valve is high -temperature and high pressure. It is a unique and tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The power station swing check valve -type stop valve has the design characteristics of ordinary spinning -type stopping valve. The valve petals rely on the flow of the medium to open and close the valve. Because the valve petals do not rub with the valve seat before closed, the cover wear is reduced to effectively extend the service life of the valve.
RAYS PDS Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.
RAYS cryogenic ball valve with extended bonnet ball valve will bring you a huge gain in the field of cryogenic LNG service. Service temperature from -51° to -196°C (-59,8° to -320,8°F) with extended bonnet design.
