Zhejiang Vituli Valve Manufacturing Co., Ltd. successfully developed the "double valve stem insulation jacket cut-off valve".
The double valve stem structure has the following characteristics: First, the lower valve stem is an integral structure, the concentricity is high, the cone sealing can be realized, the closing force is small, and the sealing is reliable; the second is that the valve body body parts can achieve smoothness and no medium crystal dead angle, It can effectively prevent the crystallization of the medium; the third is that the lower valve stem can only be used for lifting and lowering, the sealing part is sealed, the life is long, the structure is compact, and the manufacturing process is good; the fourth is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport High-viscosity medium that will solidify at room temperature; fifth, the jacket is welded between the flanges on both sides of the valve, and the side or bottom of the valve has a jacketed connection port, and the jacket can freely flow through steam or other heat. The insulation medium ensures that the viscous medium flows smoothly through the valve.
