Product overview;
Flameproof electric floating ball valve is mainly used to cut off or connect the medium, and can also be used for fluid regulation and control.
Product features
• the valve body adopts casting, forging and other production processes, and the connection methods include flange, welding, quick assembly, thread and other connection methods.
• the ball core only needs to rotate 90 ° around the valve axis to complete full opening or full closing, with simple and rapid action;
• the sealing ring adopts unique elastic lip sealing technology to ensure the cut-off requirements of zero leakage, and the unique automatic compensation function makes the valve have a longer service life;
• sealing ring materials include PTFE, reinforced PTFE and hard seal, which are suitable for various working conditions.
• after surface hardening treatment, the ball core is smooth and wear-resistant after grinding and polishing;
• the inner diameter of the flow passage is the same as that of the straight through ball type pipe;
• the built-in valve stem has better safety and rigidity;
• because the ball core and sealing ring have shear effect in the switching process, it is especially suitable for pulp, sewage and other slurry fluids with particles;
• anti static devices can be installed according to user requirements;
