On August 23, 2024, under the witness of representatives: from SGS, the National Valve Quality Supervision and Inspection Center (Zhejiang), and the project owner – a batch of large-diameter high-pressure 40″-900Lb metal seated zero leakage ball valves from RAYS exceeded expectations by passing multiple Factory Acceptance Tests (FAT). This includes: hydraulic pressure performance tests, low-pressure air tests, stem packing fugitive emission tests, and torque tests. During the tests, this batch of products achieved leakage rating A and met the low…

Recently, RAYS successfully delivered a batch of pneumatic ball valves to an international customer. This project will transport liquefied natural gas along the Northern Sea Route. To adapt to the harsh Arctic weather, these pneumatic ball valves are not only capable of stable operation in Cryogenic environments but also come with customized pneumatic actuators for quick opening and closing. Given the flammable and explosive nature of liquefied natural gas, in order to meet customer demands and ensure equipment safety during…

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…

RAYS has recently completed a significant delivery of specially designed control ball valves and ultra-high temperature ball valves. These products are destined for critical applications in the chemical, oil, and natural gas industries. The high-temperature hard-sealed control ball valve utilizes advanced principles of fluid dynamics and material science to ensure superior performance under varying temperatures and pressures. Our designs include: Control Hole Valve Seats: These seats segment the fluid flow into smaller units, smoothing the flow and reducing both turbulence…

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,…

RAYS recently successfully signed a valve order for export to Poland, including lift plug valves and three-way lift plug valves. This batch of plug valves is suitable for various industrial applications, including chemical, oil, and natural gas processing. The lift-type plug valves have optimized fluid dynamics performance, reducing fluid resistance, enhancing fluid transportation efficiency, and reducing energy consumption and wear during operation. Moreover, their unique lift structure allows the plug to disengage from the seat during the opening and closing,…

Recently, RAYS has delivered a batch of on/off control valves for hydrogen mixture devices to overseas customers. This batch includes high-pressure ball valves and high-temperature globe valves. The reliable operation of the on/off control valves is critical to the safety and stability of the entire system. Given the flammability and explosive nature of hydrogen mixture devices and their complex operating conditions, RAYS utilizes electric or pneumatic actuation mechanisms to achieve programmed, automatic, and remote control of the valves. Based on control signals…

Recently, RAYS successfully delivered a batch of high-quality rising stem ball valves, totalling 60 units, designed explicitly for hydrogen. This accomplishment showcases RAYS’ outstanding production capabilities and R&D prowess. These rising stem ball valves have nominal diameters ranging from NPS 1” to 16”, with pressure classes from CL 300 to 1500. They feature a top-entry design that ensures durability and excellent sealing performance. The order includes two 16” 1500lb rising stem ball valves, notable for their large size and high…
