1. The unique jacket structure design enables the introduction of steam, heat transfer oil or other insulation media, effectively maintaining the fluid temperature inside the pipeline and preventing the medium from solidifying or losing heat.
2. It adopts PTFE (polytetrafluoroethylene) or metal hard sealing valve seats, which are resistant to high temperatures and corrosion, ensuring no leakage during long-term use and meeting the requirements of harsh working conditions.
3. The valve body is forged from high-quality stainless steel or carbon steel and undergoes special heat treatment processes, with a high-temperature resistance of over 300℃, strong pressure-bearing capacity, and suitability for high-pressure pipeline systems.
4. The full-diameter structure design ensures that the fluid passage is consistent with the inner diameter of the pipeline, reducing pressure loss and ensuring smooth fluid flow, suitable for high-viscosity or easily crystallizing fluids.
5. It provides various driving methods such as handles, worm gears, pneumatic or electric, with flexible opening and closing and rapid switching. The modular design is convenient for disassembly and maintenance, reducing usage costs.
6. The surface of the ball is hardened, wear-resistant and corrosion-resistant, and the valve stem has a blowout prevention design, ensuring long-term stable operation, reducing failure rates and replacement frequencies.
7. It is suitable for steam, heat transfer oil, chemical fluids, petroleum, food and other industries, meeting the needs of different media and temperature environments.

RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
An energy-saving control valve without external energy sources, used for flow control in process equipment involving non-corrosive liquids, gases, steam, etc.
Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
