About lined globe valve

   Fluorine-lined Butterfly Valve To withstand high temperatures, it is necessary to use a hard seal, but with a large amount of leakage; To achieve zero leakage, soft seals must be used, but they are not resistant to high temperatures. To overcome the contradiction of the double eccentric butterfly valve, a third eccentricity was applied to the butterfly valve. check valve Its structural feature is to cause the conical axis of the butterfly plate sealing surface to deviate from the cylindrical axis of the body while the double eccentric valve stem axis is eccentric, that is to say, after the third eccentricity Clamp type fluorine lined butterfly valve The sealing cross-section is no longer a true circle, but an ellipse, and its sealing surface shape is therefore asymmetric, with one side inclined to the centerline of the body and the other side parallel to the centerline of the body.

Plastic lined J41 straight through, J45 straight slip, J44 angle globe valves have the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of nominal diameter). Widely used as a cut-off medium in pipeline systems such as petroleum and chemical industries, plastic lined globe valves are strictly prohibited from flow regulation to prevent high-speed medium flow generated at the throttling port from eroding and damaging the sealing surface. Valve disc and PTFE lined valve The rod is designed as an integrated structure to prevent the possibility of internal components rushing out of the valve body due to pressure fluctuations in the pipeline. The structure is compact and safe to use.
 
 
   Fluorine lined DC globe valve Also known as a shut-off valve, it is a widely used type of valve. Its popularity is due to the low friction between the sealing surfaces during the opening and closing process, its durability, small opening height, easy manufacturing, and convenient maintenance. It is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc with the sealing surface of the valve seat, preventing the flow of the medium. The shut-off valve only allows one-way flow of the medium and has directionality during installation. Its structural length is greater than that of a gate valve, and at the same time, it has high fluid resistance. During long-term operation, its sealing reliability is not strong
