1. Low torque operation - Rotating valve seat design, easy and effortless opening and closing
2. Bidirectional zero leakage - Precisely ground sealing surfaces, in line with international standards
3. High pressure and high temperature resistance - Maximum pressure rating of PN100, temperature range of -196℃ to 550℃
4. Long service life - Hardened ball body, self-compensating valve seat design
5. Full diameter flow - Flow channels are of the same diameter as the pipeline, resulting in low pressure drop
6. Multiple drive methods - Supports manual/ pneumatic/electric control
7. Easy maintenance - Modular design, valve seats can be replaced quickly

The Top Entry Cryogenic Floating Ball Valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
RAYS Top Entry Cryogenic C-Type Ball Valve is a specially designed ball valve suitable for ultra-low temperature environments, especially for the control of cryogenic fluid media such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen. The characteristic of the top entry C-Type C-Type ball valve lies in its special structural design.
