The Beloit 1RR605 Actuator Diaphragm is a replacement diaphragm for Beloit diaphragm‑type actuator assemblies used in industrial control valves. The part, also listed as 1RR605-1, features a 17-inch diameter and is designed to fit Beloit actuator configurations that require this spare diaphragm. Typically used in pneumatic actuation systems, the diaphragm serves as the flexible barrier within the actuator, translating control air pressure into valve movement when installed as part of the Beloit actuator assembly.
