Recently, RAYS successfully completed a significant delivery by supplying CNOOC with a batch of customized high-performance pneumatic plug valves. These valves are specifically designed for the renovation of the tank area in the CNOOC Daxie Petrochemical Distillate Oil Phase V Project, which includes product upgrades and expansion engineering. This delivery highlights RAYS’s extensive expertise and proficiency in valve design and manufacturing.The pneumatic switch plug valves have been customized to meet the specific requirements of the CNOOC project. They incorporate a pressure-balanced inverted cone design that guarantees efficient shut-off performance even in demanding conditions. Operating these valves is simple and dependable, as they only require a 90-degree rotation of the valve stem to open or close.The valve design incorporates a grease injection mechanism that uniformly applies a dense oil film across the sealing surface through a specialized oil groove on the plug surface under pressure. This feature ensures bidirectional sealing, minimizes friction over time, and provides efficient lubrication, adhering to the ISO 15848-1 Class B low leakage standard for enhanced safety and environmental protection.The larger end of the plug is equipped with a small orifice that allows the pipeline medium to lift the plug against the inverted cone surface, aiding in sealing and reducing operational torque. Additionally, a check valve located at the smaller end of the plug enables the pipeline medium to increase grease pressure in the upper chamber when necessary, balancing pressures and extending the valve’s operational lifespan.The plug surface undergoes rigorous nitriding and nickel-phosphorus alloy plating treatments, significantly enhancing hardness and wear resistance, even in high-pressure, high-frequency environments. The valve stem, made from 17-4PH martensitic precipitation-hardened stainless steel, is robust and durable, making it suitable for high-load conditions. Its blowout-proof design and triple-seal structure further enhance the valve’s durability and sealing performance.In consideration of the specific requirements of the petrochemical industry, these valves are equipped with a bottom adjustment rod that supports the plug and aids in dissipating static electricity, effectively reducing safety risks. They are designed with fireproof features and fully comply with the API 6D international standard, ensuring superior safety in project applications.This successful delivery was achieved through close collaboration and comprehensive technical discussions between RAYS and CNOOC.

RAYS has recently delivered a batch of extra-large slab gate valves to overseas clients. These valves incorporate a parallel single gate and floating seat design, enabling bidirectional operation. They are designed to ensure reliable sealing, flexible operation, and ease of use in opening and closing.The gate valves support nominal diameters up to DN1200 and include specially designed flow holes to optimize fluid dynamic characteristics. When fully opened, the pipeline’s alignment with the gate’s flow holes mimics a straight pipe, thus minimizing flow resistance. This design significantly reduces overall pressure loss within the system, decreases energy consumption, and enhances system efficiency and performance.The slab gate valves feature a precision-closing mechanism where the gate vertically moves through a precise guide system. This mechanism drastically reduces the friction coefficient and wear during operation. The sealing surfaces of the seats offer options between dual soft seals or a combination of soft and hard seals, facilitating a dual-seal effect on each seat surface. The floating seat design enables the inlet side seat to move toward the gate under medium pressure when the valve is closed, creating a substantial sealing pressure ratio and establishing the primary seal. Concurrently, the gate presses against the outlet side seat to form a robust double seal. The valve’s stem uses composite packing for enhanced sealing, ensuring reliability and minimal friction. The innovative double-seal structure also facilitates the replacement of wearable parts without impacting the pipeline operation, distinguishing our products from similar offerings domestically and internationally.As the global demand for high-performance, reliable industrial valves grows within the energy and chemical sectors; RAYS is committed to continuously enhancing product designs and expanding production capacity to meet market needs.
