RAYS pigvalve 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 ultra-low temperature swing check valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
