●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
