PVC valve plastic
Plastic valves refer to valves made of plastic materials, which are corrosion-resistant, high-temperature-resistant, light and easy to install.
Plastic valves refer to valves made of plastic materials, which are corrosion-resistant, high-temperature-resistant, light and easy to install.
With the increasing proportion of plastic pipes in hot and cold water supply and industrial pipeline engineering applications, the quality control of plastic valves in plastic pipeline systems is becoming more and more important.
Due to the advantages of plastic valves such as light weight, corrosion resistance, no adsorption of scale, integrated connection with plastic pipes and long service life, the application advantages of plastic valves in plastic pipe systems for water supply (especially hot water and heating) and other industrial fluids are unmatched by other valves.
At present, there is no reliable method to control the production and application of plastic valves in China, resulting in uneven quality of plastic valves for water supply and other industrial fluids, causing lax closure and serious leakage in engineering applications, forming a saying that plastic valves cannot be used, affecting the overall development of plastic pipeline applications. The national standard for plastic valves in my country is in the process of being formulated, and its product standards and method standards are formulated in accordance with international standards.
The types of plastic valves in the world mainly include ball valves, butterfly valves, check valves, diaphragm valves, gate valves and stop valves, etc. The main structural forms include two-way, three-way and multi-way valves, and the main raw materials are ABS, PVC-U, PVC-C, PB, PE, PP and PVDF, etc.
As long as the selection of raw materials and product control are carried out in accordance with international standards, plastic valves can fully meet the use requirements of plastic pipelines.
