The bellows globe valve WJ40F1.6P is a hydrogen pipeline valve mainly used in high-purity gas systems, including but not limited to hydrogen systems in power plants. This valve has a dual sealing design, which can completely cut off fluid flow, prevent medium leakage, and ensure the safe operation of the system. Its working principle is to drive the valve disc to open and close by the up and down movement of the valve stem. When the valve stem moves upward, the channel opens and fluid can flow through; When the valve stem moves downwards, the channel closes and fluid cannot pass through. The valve stem of this type has a relatively short opening or closing stroke, which can quickly achieve opening and closing, improving work efficiency.

In addition, the bellows globe valve WJ40F1.6P has structural advantages compared to ordinary globe valves. It includes a bellows, which allows the valve to withstand certain deformation in high temperature and high pressure environments. By controlling the degree of deformation of the bellows, it can achieve cutoff control of hydrogen gas. The ordinary shut-off valve mainly achieves shut-off control of hydrogen gas through the movement of the valve disc, which is suitable for general hydrogen gas systems.

The main material of the bellows globe valve WJ40F1.6P is 316L stainless steel, with a sealing surface of polytetrafluoroethylene and a nominal pressure of 1.6MPa. It is suitable for hydrogen and various high-purity gases and is mainly used as a valve in the hydrogen system of generators. Its applicable medium includes hydrogen, and it is widely used in industries such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, and food.
