◎Excellent sealing performance, using metal bellows as the key sealing component, with its lower end welded to the valve stem assembly and its upper end connected to the
Plate welding forms a metal barrier to prevent fluid medium leakage and achieve zero
leakage of the valve stem
◎The main components such as the valve body are made of forged steel with high structural strength, resulting in a more uniform structure, better density and strength integrity, and dimensional errors small, with better performance compared to castings, able to withstand higher pressure and temperature
◎ Easy and reliable operation
The dual guarantee of long service life with corrugated pipe sealing and packing sealing
reduces the risk of leakage and lowers the frequency of maintenance; Valve body and
◎The minimum wall thickness design of the valve cover meets the requirements of relevant standards, ensuring the strength and rigidity of the valve under harsh working conditions such as high temperature and high pressur

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.
The Cryogenic and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
Triple Eccentric Metal Seated Butterfly Valve is the newly-developed long-life and energy-saving products. The sealing is metal to metal, which couldbe changed to be seal ring to metal, stainless steel plate and composite graphite to metal. Under the working condition of high temperature and high pressure, it still has a stable sealing performance. Our company adopts optimization design and new technology, so that the torque is small, gainning the point of energy-saving, labor-saving and reliable sealing performance, thus to ensure the high-reliability of corrosion-resistantance, stand fire and wear-resistantance. This product is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
