Bellows stop valve steam selector spesak valve Toyama valve

  1、 Wj41y heat transfer oil stop valve introduces foreign advanced technology and adopts double-layer bellows design
It is welded to the valve stem to maintain stable operation performance and avoid valve stem vibration caused by valve plug vibration
Under high temperature, the valve rod does not contact with the medium to ensure zero leakage of the valve rod
At the same time, it ensures sufficient strength and toughness, which can be switched on and off for tens of thousands of times
The hand wheel adopts ergonomic design, with longer service life and easy and convenient operation

2、 Working principle of heat transfer oil stop valve the inside of the heat transfer oil stop valve adopts bellows structure, and the lower end of the stainless steel bellows is welded on the valve stem to prevent the process fluid from etching the valve stem
The other end is placed between the valve body and the valve cover to form a static seal
Double sealing design is adopted
If the bellows fails, the valve rod packing will also avoid leakage
The bellows is welded to the valve rod to maintain stable operation performance and avoid valve rod vibration caused by valve plug vibration
