High Flow 3/8", 1/2", & 3/4" Precision Regulators


Maintain your desired output pressure with the direct acting, diaphragm-operated ARO High-Flow Precision Regulator


  • Flow rates of up to 200 scfm 
  • Rugged die-cast zinc and aluminum housings are pressure tested for safe operation and can handle harsh and abusive environments. The ARO high-flow precision regulator is designed for applications that require large flow capability and accurate pressure control. With low droop, high accuracy, fine adjustment control, these units are excellent in material handling and conveyor applications. The use of a rolling diaphragm provides excellent sensitivity and improved accuracy while a balance pintle minimizes output pressure changes caused by fluctuations in the supply pressure. With a maximum supply pressure of 400 psig (22.7 bar) and output ranges up to 125 psig (8.6 bar) flow rates of 200 scfm can be achieved.
