The 40FJ-1.6PA2 Steam turbine stainless steel globe valve flange is a corrugated tube type sealing valve used for the stainless steel main valve body material. It is mainly used for the hydrogen cooling system of large steam turbines and generators. The hydrogen leakage rate of the hydrogen system is an important indicator for assessing the installation quality of the unit.

 

Structure specification of  Steam turbine stainless steel globe valve flange 40FJ-1.6PA2 

 

1. When the handwheel is turned clockwise, the valve stem moves downward and the valve disc descends to seal the sealing surface, cutting off the passage. When reversed, it opens and the valve stem is lifted to the highest point for sealing to take effect.

2. This valve has added an upper seal. When the valve is open, it has two layers of sealing effect together with the packing, and has a certain protective effect on the packing.

3. This valve uses nylon products as the sealing surface, and the filler is soft formed filler. The upper seal is also made of soft material, with good sealing performance.
