Our standard PFA lined Diaphragm range is Ideal for throttling and flow control requirements. Diaphragm Valves combine accurate throttling of flow with positive shut-off. The streamlined flow passage creates minimum pressure drop, and the compressor is carefully matched to wier contour to exert uniform pressure on the diaphragm, increasing diaphragm life. Also, these self draining valves have no crevice where particles can be collected, that means cleaner operation. All of the valve’s operating parts are completely isolated from the process stream. Our Diaphragm Valves were specifically designed to keep hazardous or corrosive fluids contained. The fluid being handled is completely sealed off from the outside environment by a thick, inert floropolymer liner and the diaphragm. Since there is no stem in the fluid stream, stem leakage problems are eliminated.
