The types of plastic valves in the world mainly include ball valve, butterfly valve, check valve, diaphragm valve, gate valve and globe valve. The structural forms mainly include two-way, three-way and multi way valves. The raw materials mainly include ABS, PVC-U, PVC-C, PB, PE, PP and PVDF.
In the international standards for plastic valve products, first of all, the raw materials used in the production of valves are required. The manufacturers of valves and their raw materials must have creep failure curves that meet the plastic pipe product standards; At the same time, the sealing test, valve body test, long-term performance test, fatigue strength test and operating torque of the plastic valve are specified, and the design service life of the plastic valve used for industrial fluid transportation is 25 years.
Plastic valves do not absorb scale, can be integrated with plastic pipes and have a long service life. Plastic valves have advantages in application in plastic pipe systems for water supply (especially hot water and heating) and other industrial fluids that other valves cannot match.

·PVC ball valve (two-way/three-way)
PVC ball valve is mainly used to cut off or connect the medium in the pipeline, as well as to regulate and control the fluid. Compared with other valves, it has small fluid resistance and the ball valve has the smallest fluid resistance among all valves. In addition, UPVC ball valve is a ball valve product developed according to the requirements of various corrosive pipeline fluids.

·PVC butterfly valve
Plastic butterfly valve has strong corrosion resistance, wide application range, wear resistance, easy disassembly and simple maintenance. Applicable fluid: water, air, oil, corrosive chemical liquid. The valve body structure adopts the central line type. Plastic butterfly valve is easy to operate, with tight sealing performance and long service life; It can be used to quickly cut off or adjust the flow. It is suitable for occasions where reliable sealing and good regulation characteristics are required.
