First, Lined fluorine ball valve overview
Ball valve is used with a circular hole for the opening and closing of the ball, the ball with the valve stem around the center line of rotation in order to achieve the valve to open and close. Our ball valve series for the Q41 type, for the two open structure.
1, using a special molding process, so that the sealing surface is dense and good, combined with V-PTFE packing valve to achieve zero leakage.
2, the ball and stem casting as a whole, put an end to pressure stem stem out of the possibility of pressure within the pressure parts, the fundamental guarantee of safety.
3, the use of all plastic lining technology, resistant to strong corrosion.
