Cast steel Ball valve Main parts and materials

Cast steel Ball valve refers to a floating ball valve with a cast steel valve body. These valves are primarily designed for low-pressure service with a flexible temperature range. usually equipped with flanged end connections，manual operation (lever or gear) is adopted. Due to the low pressure level and small size, the torque to open or close the valve is not large, so  Generally speaking, Cast Steel Floating Ball Valve is mainly used for switching applications and smaller throttling purposes.

The principle of cast steel floating ball valve

The floating ball of this ball valve is supported by two valve seats. Under the action of the medium pressure, the ball itself produces a certain displacement and presses on the valve seat sealing ring at the outlet to ensure the sealing at the outlet.

Cast steel Ball valve design

Floating ball, cast steel, split (two or three pieces) / single body (one piece, whole). Side entry, end entry or jack entry, full bore (full bore)/reduced bore (reduced), RF, RTJ or BW. Lever or gear operation, fireproof design, explosion-proof valve stem, low emission control and anti-static.

Size range: 1/2" (DN15) to 12" (DN300);

Pressure rating: Class 150 ~ Class 300 (PN16 ~ PN40).
