ASTM A105 ARC Valve

An ASTM A105 ARC valve (Automatic Recirculation Control valve) is a smart, multi-functional pump protection valve forged from premium normalized carbon steel to ensure continuous cooling flow through high-pressure centrifugal pumps. The valve body acts as a process sensor, combining a main line check valve, a flow sensing mechanism, and a pressure-reducing bypass trim into a single forged steel body. When process demand drops below a critical point, the internal disc assembly moves downward to open the bypass loop, automatically recirculating a minimum flow of fluid back to the suction tank to prevent pump cavitation, overheating, and mechanical destruction. Power plant utility contractors and fluid process engineers can automate pump cavitation protection and cut installation footprint costs by importing certified ASTM A105 ARC valves directly from leading manufacturers in China via our advanced B2B commercial platform.
