Overview of F46 Lined Ball Valve The ball valve uses a sphere with a circular through-hole as the opening and closing member. The sphere rotates around the centerline of the valve body along with the valve stem to achieve opening and closing of the valve. This company's lined ball valve series is the Q41F46 type, featuring a split two-piece structure. Structural Features 1. Adopting a special FEP molding process ensures good compactness of the sealing surface. Combined with the V-shaped PTFE packing set, the valve achieves zero leakage. 2. The sphere and valve stem are cast as a single unit, avoiding the possibility of the valve stem being blown out of the pressure-containing parts due to pressure changes, thus ensuring operational safety. 3. Adopting a full lining process, it can withstand any strong corrosive media except "molten alkali metals and elemental fluorine." Design Standards Complies with GB12237/API608/API6D standards. Actuation Methods Manual, worm gear, pneumatic, electric.
