●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

An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
The Insulation Jacket Ball Valve is specially designed for pipeline systems that require maintaining the temperature of the medium. It is made of high-quality stainless steel or carbon steel and combines with precise processing technology to ensure reliable sealing and smooth control under high-temperature and high-pressure conditions. The valve body adopts a jacketed insulation structure and can be filled with steam or heat transfer oil, effectively reducing heat loss. It is suitable for high-temperature fluid transportation systems in industries such as chemical, petroleum, heat supply, and pharmaceuticals. The structure is compact, the opening and closing is rapid, the sealing performance is excellent, and it is an ideal control valve for high-temperature fluid pipelines.
The Non-Rising Stem Gate Valve is also called the rotating stem gate valve. Stem and nut are arranged on the gate plate, handwheel rotation drive valve stem rotate to lift the gate, usually there is a trapezoidal thread at the bottom of the valve stem and the rotation movement is turned into a linear motion through the limit slot between the valve stem and the gate body and the gate body and the gate, that is, the operation torque is turned into operation thrust. When the valve is turned on, when the height of the gate is equal to the diameter of the valve 1: 1: 1, the channel of the fluid is completely unblocked, but at the run, this position cannot be monitored. In actual use, the vertex of the valve stem is used as a sign, that is, the position that is unmoved as its full opening position. The non-rising stem gate valve has the design characteristics of the ordinary wedge-type gate valve. The valve body has a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
