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


  • Flow rates of up to 200 scfm 
  • The ARO high-flow precision regulator is a direct acting, diaphragm-operated regulator. Once set to a desired output pressure, the regulator maintains the setting permanently 
  • Available in 3/8", 1/2", and 3/4" NPT 
  • 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.
