The root of the Rubber Diaphragm is to prevent inappropriate contact between different medias (such as gas and fluid) and should be flexible enough to create mobility during flow control. Tensile and elongation of rubber allows it to control and control various pressures during operation and work. We have a lot of years of experience in the manufacturing of Rubber Diaphragms, including reinforced and unreinforced flexible rubber diaphragms. All our diaphragms are manufactured under strict quality control to ensure zero rejection of the medieval life cycle and longevity.
