There is no reliable method to control the installation and application of plastic ball valve in domestic pipeline production and application, resulting in uneven product quality of plastic ball valve pipeline for water supply and other industrial fluids, resulting in lax closure and serious leakage in engineering application. The national standard of plastic ball valve pipeline is in the process of formulation, and its product standard and method standard are in accordance with the national standard International standards.


The minimum diameter of reducing plastic ball valve is DN 15-dn300. When ordering, please provide detailed requirements, specifications and dimensions, pressure, temperature, pipeline system flow medium, etc., so as to accurately and correctly select the type of plastic ball valve products. At present, the quality guarantee is 1 year. The plastic ball valve is mainly used for the design service life of domestic water supply system. Plastic ball valve pipe can fully meet the requirements of use, and there are some inappropriate points in international standards.
