Product Overview

The UPVC diaphragm valve is a type of valve whose body is made of UPVC (high-density polyvinyl chloride), and it uses an elastic diaphragm (such as EPDM, PTFE, etc.) to cut off or regulate the flow of fluids. It features corrosion resistance, light weight, and low cost. It is widely used in industries such as chemical engineering, water treatment, medicine, and food.
