Alloy Steel Ball Valve Casting

Alloy Steel Ball Valve Casting

Alloy steel hard seal ball valves are mandatory seal valves, so when the valve is closed, pressure must be applied to the valve flap to force the seal face to leak.

Alloy steel hard seal ball valves are mandatory seal valves, so when the valve is closed, pressure must be applied to the valve flap to force the seal face to leak. When the medium enters the valve six from below the valve flap, the resistance to be overcome by the operating force is the friction force of the alloy steel hard-sealed ball valve stem and packing and the thrust generated by the pressure of the medium. The force of closing the valve is higher than that of the valve. The force is large, so the diameter of the valve stem is large, otherwise the valve stem top bend will occur.


Advantages of using alloy steel hard seal ball valve:

Alloy steel hard seal ball valve adopts soft T-shaped multi-layer stainless steel sheet to form a sealing ring. It has the double advantages of metal hard seal and soft seal. The alloy steel hard seal ball valve has zero leakage at low temperature and high temperature. Sealing performance. When the test proves that the positive flow state of the tank (the direction of flow of the medium is the same as the direction of rotation of the disc), the pressure of the sealing surface is caused by the action of the torque of the transmission and the pressure of the medium on the valve plate. When the positive medium pressure increases, the inclined surface of the valve plate and the sealing surface of the alloy steel hard seal ball valve seat are pressed tighter, and the sealing effect is better.
