Polyethylene is used extensively for fabrications and pipeline systems in water drainage, water supply & gas supply systems. Polyethylene has a large operational temperature range and a low specific weight. The material has excellent chemical resistance and a high abrasion resistance. Polyethylene can be readily joined using butt fusion, socket fusion and electro-fusion welding techniques or mechanical assemblies.   Features of PE ball valve:                                                                                                             1.Without leakage,Safe, Enviorment protection                                                                         2.Longer service life than metal valves                                                                                           3.Excellent anti-corrosive performance                                                                                       4.Much lighter than metal valves
