The opening and closing part of the J41H bellows globe valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the center line of the valve seat. The movement form of the valve stem, (common name: dark rod), also has a lifting and rotating rod type, (common name: rising rod), a stop valve refers to a valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke.
·It is made of low-temperature steel and corrosion-resistant alloy, and is integrally cast by precision steel casting process, which increases the corrosion resistance by more than 80%;
·The built-in bellows in the valve cavity can completely block the possibility of medium leakage. It has a double sealing structure, maintenance-free and no leakage;
·The valve disc and valve seat are respectively made of strong corrosion-resistant PTFE and Stellite cemented carbide;
·Using multi-layer hydraulic bellows forming technology combined with advanced and mature process design;
·The middle flange adopts birch groove sealing design;
·Adopting the guiding design of the rotation movement and the axial movement, the disc seal adopts the cone first and then the plane type, and the automatic compensation design of the equipped seal is applied.
