C-type Structure: The valve body of the C-type ball valve is designed to be similar to the shape of the English letter "C". This design helps to reduce fluid turbulence and pressure loss, while facilitating cleaning and maintenance.
Top-loading Design: The main components such as the ball and valve seat can be removed and installed from the top of the valve body,
which is convenient for maintenance and replacement without removing the pipeline.
Fixed Ball Design: The ball is fixed in the valve body and does not rotate with the flow of fluid, which helps to reduce the erosion of the ball by the fluid and extend the service life of the valve.
Ultra-low Temperature Materials: The valve is made of stainless steel, nickel-based alloy and other materials suitable for ultra-low
temperature environments, and uses sealing materials with good low temperature performance, such as PCTFE.
Thermal Insulation: The valve may be equipped with a thermal insulation layer to prevent external heat from entering the fluid and maintain
the fluid at an ultra-low temperature.

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.
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.
RAYS' rising stem ball valve is designed to operate without friction between the ball and the seat during opening and to achieve zero leakage when closed. This makes it well-suited for demanding conditions. The valve is made entirely of metal and is fire-resistant, capable of functioning in extreme temperatures ranging from -196°C (320.8°F) to 538°C (1000.4°F). It can handle media with particulates like sand and short fibers, and meets NACE standards for corrosion resistance, ensuring it can resist sulfide stress cracking in harsh environments. The valve also features a self-cleaning mechanism. When the ball is tilted away from the seat, the fluid flows 360° around the ball's sealing surface, effectively removing any debris. This prevents damage from high-speed fluid flows and keeps the sealing area clean. The rising stem ball valve is ideal for various applications including exhaust, fluid transfer, pipeline isolation, bypass, product segmentation, and emergency shutdowns, particularly where high switching frequencies and zero leakage in high temperatures are required.
