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.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
The low-temperature single-seat regulating valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
