Descriptions And Features Of UPVC Wafer butterfly Valve :
UPVC butterfly valve is a type of valve made mainly of polyvinyl chloride. It is widely used to control the flow of liquids or gases in pipelines. This valve has the characteristics of corrosion resistance, anti-aging, and light weight, and is particularly suitable for scenarios such as water supply, sewage treatment, and irrigation systems. Its structure is simple, and it can be operated by rotating the handle, with good sealing performance, effectively preventing leakage.
UPVC material complies with national drinking water hygiene standards. Its inner wall is smooth and free of deposits, and it is suitable for scenarios with strict hygiene requirements such as the food industry and drinking water treatment.
Design Features Of UPVC Wafer butterfly Valve :
1. The valve body of the plastic butterfly valve requires only a minimal installation space and its working principle is simple and reliable..
2. The approximately equal percentage flow characteristic can be used for regulating or on-off control.
3. The valve body of the plastic butterfly valve is in accordance with the standard convex surface pipe flange.
4. Resistant to wear, easy to disassemble, and simple and convenient for maintenance.
5. The material is hygienic and non-toxic, lightweight, and easy to install.
