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 Blind Valve features an advanced design for quick and safe flow isolation or fluid control within pipelines. At the heart of the valve is a blind plate that can be swiftly moved in and out by turning a handwheel. To isolate the flow, simply turn the handwheel and the blind plate will slide along a track to the center of the pipe, creating a seal that blocks fluid flow. This operation does not require any special tools, nor does it involve dismantling heavy machinery or dealing with complicated bolts and nuts. The design of the blind plate ensures a stable and reliable sealing performance in any working condition, greatly simplifying the operation and reducing operational risks. The simplicity and durability of the structure also make maintenance straightforward, reducing both maintenance costs and downtime.
An energy-saving multi-combination control valve without external energy sources, used for flow and temperature control devices for non-corrosive liquids with a maximum temperature of 350℃, as well as pressure and differential pressure control devices, and flow and pressure control devices for liquids, gases and steam.
