FRPP Plastic Flanged Diaphragm Valve Descriptions

FRPP plastic flanged diaphragm valve is manufactured according to HG/T2643-2010, which is extruded and formed from raw materials of high quality fiber glass FRPP. FRPP overcomes the small mechanical strength of PP, but keep the PP good anti-corrosion performance, and increase the working temperature (-14 ~ +90℃). FRPP flanged ends diaphragm valve is featured with high mechanical strength, good anti-corrosion, small cost, long service and easy installtion. This type of plasti diaphragm valve is first choice in the anti-corrision pipes in the fields of petroleum, chlorine alkaline, chemical fiber, fuel, pesticide, light industry, water treatment. Flowspec Luokai can manufacture and supply the FRPP plastic flanged diaphragm valve with sizes of  1/2”~10”(DN15~DN250mm). Welcome to contact us for detailed information and best quotes if you have any questions or inquiries.
