RAYS Top Entry Cryogenic Trunnion Mounted Ball Valve is a type of valve widely used in cryogenic piping systems, especially suitable for the on/off control of cryogenic liquid or gas media such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen, and liquid oxygen. Its design features include a top-entry valve body structure for easy online maintenance, an extended bonnet design to prevent condensed water from flowing into the insulation layer, a live-loaded sealing structure design for the valve stem, and a special design of the valve seat assembly.
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
C700 Single Seated Control Valves are a top-guided single-seat valve. This series of products has absorbed the advantages of similar products at home and abroad and has been improved and innovated. In terms of design, process, and assembly, it has reached the advanced level of similar products domestically and internationally. It has a compact structure, small volume, smooth flow channel, and the fluid passage is in an S-shaped streamline. The flow characteristic curve has high precision, is stable and reliable, and is easy to maintain.
