There is an oil groove between the valve body and the sealing surface of the pressure-balanced plug valve, and sealing grease can be injected into the valve seat through the oil nozzle at any time to improve the sealing performance. The material of the parts and the size of the flange can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
RAYS pig valve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
