Q41WC series hard seal pneumatic ball valve uses integral valve seat instead of free valve seat. The integral valve seat can provide a stable platform on which the valve ball bears high pressure to prevent solid blockage between the valve ball and the valve seat. When the valve ball is in the open state, the valve seat shall be free from the harm of medium. The integral valve seat also eliminates the possibility of leakage between the free valve seat and the valve body.

Most of the time, the product is mainly used for the control of solid materials.
