ATRF series diaphragm valve CPVC diaphragm valve commonly known as chlorinated polyvinyl chloride diaphragm valve, also known as CPVC plastic diaphragm valve, CPVC resin after chlorination, molecular bond irregularity increases, polarity increases, so that the solubility of the resin increases, chemical stability increases, thus improving the material heat resistance, acid, alkali, salt, oxidant and other corrosion.Therefore, CPVC is a new type of engineering plastics with broad application prospects.
