Beloit 1RR605 Valve Diaphragm is a replacement diaphragm component for Beloit valve assemblies, offered as new-old-stock with the part number 1RR605 (a variant is listed as 1RR605-1). A catalog-style listing for this part notes a 17-inch diaphragm diameter, identifying the 1RR605 family and its associated fitment in large-diameter Beloit valves. As a diaphragm valve element, this component functions by flexing the diaphragm to seal against the valve seat under control pressure, enabling pneumatic actuation and flow control in the system. When selecting a replacement, confirm compatibility with your specific Beloit valve model that specifies the 1RR605 diaphragm to ensure proper fit and sealing performance.
