RAYS bellows sealed globe valve adopts international advanced technology and double sealing design. It has the characteristics of high-performance elastic metal bellows and extremely long expansion fatigue life. Pipe shut-off valves: improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs & frequent maintenance, and also provide a clean & safe work environment. Bellows sealed globe valve are suitable for class 150~2500, working temperature -46°C~538°C pipeline. Using carbon steel, stainless steel and other different main materials can be suitable for various media. The optional drive devices are: hand wheel, electric, pneumatic, etc. Bellows sealed globe valves are suitable for pipelines under various working conditions in petroleum, chemical, pharmaceutical, fertilizer, electric power, and other industries.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
