Lined ball valve: A spherical body with a circular passage is used as the opening and closing member. The sphere rotates around the centerline of the valve body along with the valve stem to achieve valve opening and closing. A special molding process ensures a tightly sealed surface, combined with V-type PTFE packing that allows the valve to reach zero leakage; the sphere and valve stem are cast as one piece, eliminating the possibility of the valve stem being pushed out of the pressure-bearing components due to pressure changes, ensuring safety during use; a fully plastic lining process provides strong corrosion resistance to the medium.
Drive: Lined ball valves can be operated manually, via worm gear, pneumatically, or electrically.
Features: 1. Ball valves with fluoroplastic lining have extremely high chemical stability and are suitable for any highly corrosive chemical media; 2. Full-bore floating ball valve structure enables zero-leakage closure across the entire pressure range, facilitating pipeline system pigging and maintenance.
Applications: Lined ball valves are specially designed to control the opening and closing of various highly corrosive media and are widely used in industries such as petroleum, chemicals, dyeing and chemical, pesticides, acid and alkali production, making them an ideal choice for corrosion-resistant valves.
