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.

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 Cryogenic Temperature 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.
