In LNG cryogenic service, sealing performance is governed by long-term stability rather than material strength.At -196C, thermal contraction, elasticity loss, and interface variation continuously alter sealing conditions, making consistency the key challenge rather than initial tightness.RAYS addresses this through spring-loaded seats, a dual sealing system (lip seal + graphite), and an extended stem design that compensates for thermal effects and stabilizes sealing behavior over time.…

Most valve failures are not sudden, but the result of progressive degradation under repeated operating cycles. In high-pressure service, a key issue arises when sealing and motion occur simultaneously, leading to continuous friction, wear, and unstable sealing over time.RAYS top-entry rising stem ball valves (2–8", Class 300), recently delivered in a batch of 54 units, are designed to address this mechanism. Motion and sealing are separated within the operating cycle: sealing interfaces remain disengaged during rotation and only engage after motion is completed.By eliminating sliding contact during movement, the design reduces wear accumulation, minimizes galling risk, and ensures more stable sealing performance under cyclic conditions. This is not a material upgrade, but a mechanism-level redesign that defines reliability from the start.…

We are packing a batch of NPS 6“-28", Class150-300 high pressure pneumatic knife gate valves for project delivery. The valves shown in this video have completed manufacturing, assembly, inspection, and pressure testing and are now entering the final stage before shipment. Designed for high-pressure gas processing complex applications, this batch is suitable for solid particle media. During the packing process, each valve is cleaned, protected, and securely crated to ensure stability and safety during transportation and site handling. This video records that final step of the project before delivery. RAYS Flow ControlInspire Infinite Possibilities…
