PVC compact ball valve is simple in structure, only a few parts, material consumption, small volume, lightweight, small size, small driving torque, easy and rapid operation, just rotate 90 ° can quickly open and close; It also has good flow regulation and off seal properties, and the PVC compact ball valve is the dominant valve type in Kingdom of Dali caliber, medium and low-pressure service.
If PVC compact ball valve is required for flow control use, the main thing is to select the correct size and type of valve. PVC compact ball valve construction principle is particularly suitable for the production of large-bore valves, valve strength performance refers to the ability of the valve to withstand medium pressure. Valves are mechanical products that can withstand internal pressure and must therefore have sufficient strength and stiffness to ensure long-term use without rupture or deformation. As an integral ball valve, PVC compact ball valve has less leakage point, high strength, and convenient assembly and disassembly. Ball valve installation: both ends of the flange and pipeline connection, to tighten the bolts to prevent flange deformation caused by leakage. The clockwise direction turns the handle to close, and vice versa. Only for the cut-off, circulation, not flow regulation. A liquid containing hard particles tends to scratch the surface of a ball.
