This set of ball valve, gate valve and cut-off valve has the advantages of a new product. The valve seat adopts body welding and is really hard-to-hard. It has the same double seal as the wedge gate valve, which is not limited by the flow direction of the medium and can be installed arbitrarily. Sealing principle with reliable sealing valve and long service life is adopted. The ball valve is pressed against the valve seat as if the valve disc is moved in parallel to the valve seat to form a seal. No scratches, little wear, no fear of sticking particles on the sealing surface. The medium, when the combination ball rotates to open the valve, there is a gap between the ball and the valve seat, and it rotates without contact, so it is more wear-free. Low operating torque and long service life.
