●The overall structure design of the valve is compact, with small external dimensions and light weight. It is not only easy to transport and install, but also effectively saves space in the pipeline system, especially suitable for working conditions with limited installation space
●The main components such as the valve body and valve cover are forged and formed using forging technology. Compared with cast steel parts, they have better quality and performance, stronger mechanical properties such as plasticity and toughness, and can withstand greater impact forces. They can meet the requirements of various harsh working conditions and are suitable for high temperature, high pressure, and harsh working environments
●The selection of sealing surface materials is reasonable. Generally, the sealing surfaces of the valve disc and seat are made of alloy steel or hard alloy butt welding, which is heat-resistant, corrosion-resistant, wear-resistant, has a long service life, and can maintain good sealing performance for a long time
●When the medium flows downstream, the valve disc opens under the thrust of the medium; When the medium stops flowing or undergoes backflow, the valve disc automatically closes under its own gravity and the pressure of the medium backflow, thereby preventing the medium from flowing back. The action is sensitive and reliable, and the opening and closing are rapid, which can effectively protect the normal operation of the pipeline system and equipment
●Multiple connection methods can be provided, such as socket welding, threading, flanges, butt welding, etc., to meet the installation needs of different pipeline systems. At the same time, the nominal pressure range of the valve is wide, from CL150 to CL2500, and the working temperature range is wide, usually between -196 ° C and+600 ° C. It can adapt to various pressure levels and temperature conditions, and can be widely used in many industries such as petroleum, chemical, natural gas, power, metallurgy, papermaking, pharmaceuticals, etc

Sleeve plug valve is a kind of precise fluid control equipment, its clever design lies in the sleeve connection between the plug and the valve body. This structure not only ensures excellent sealing performance in high-pressure environments, but also facilitates installation and maintenance. Sleeve plug valve for its reliable cut-off capacity and smooth media flow characteristics. It is mainly used for oil and gas storage and transportation in chemical industry, metallurgy, paper making, food processing and other industries, for opening or closing, and with pneumatic and electrical devices can also achieve remote operation to ensure personal safety.
Cryogenic Gate Valve is an opening and closing device used for fully opening and fully closing. The opening and closing component of ultra-low temperature gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape, and the wedge angle varies with parameters.
RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
