Easy access seat plug
The removable plug allows quick access to the ball and seat of the fluid regulator. The feature reduces downtime for cleaning or changing the seat if necessary. It also allows users to use different sized balls and seats to generate different flow rates |
Larger adjustment spring
A large diameter counter-spring is used to ensure consistent pressure output and a wide pressure range. Models can be configured with different spring options for higher performance and better regulator life. |
Tamper-resistant spring adjustment
ARO’s later industrial regulator models have a recessed hexagonal connection, which allows the pressure to be adjusted using the same 9.5 mm (3/8 in) wrench included to remove the housing. This screw is recessed to prevent accidental or unauthorized changes to the setting. |
Mode “Easy-flush”
With the unique rinse mode of ARO’s industrial back regulators, simply turn the included key clockwise to move the entire central spindle downwards, which removes the ball from the seat and eliminates particle build-up throughout the regulator. |
Base housing material options
High pressure regulator bases are available in 300 series stainless steel or zinc/aluminum. High-pressure bases are available in 300 series stainless steel or carbon steel coated in chemical nickel for greater material compatibility. All regulator seals are made of PTFE for maximum chemical compatibility. |
Easy access housing fasteners
To open our industrial regulators for maintenance or inspection, simply remove four easily accessible hexagonal screws. There is no need to remove the regulator from the line during the process. The upper housing is made of corrosion-resistant aluminum and zinc, with an elegant appearance and a long rust-free service life.

A large diameter counter-spring is used to ensure a consistent pressure output and wide pressure range capabilities. Models are configurable with different spring range options to provide enhanced performance and improved regulator life-span.
Low-pressure regulator bases are available in 300 series stainless steel or zinc/aluminum. High-pressure bases are available in 300 series stainless steel or Electroless Nickel-plated carbon steel for wide material compatibility. All regulator seals are constructed of PTFE for maximum chemical compatibility.
ARO’s industrial downstream regulator models have a recessed hex-head fitting allowing pressure adjustment using the same 3/8” wrench (included) that removes the housing. This screw is recessed, which helps avoid any accidental or unauthorized adjustment changes.
Our industrial regulators can be opened for maintenance or inspection by removing four, easy to reach hex-head screws. There’s no need to remove the regulator from the line while doing this, either. The upper housing is constructed of corrosion-resistant zinc aluminum for a sleek, clean appearance and a long, rust-free life.
Back-pressure fluid regulators are typically used in recirculating or closed loop systems, allowing them to maintain fluid pressure of the system either upstream of the fluid regulator or downstream of the dispensing device. Back-pressure fluid regulators help maintain fluid pressure regardless of changing flow demand triggered by multiple operators or dispense points.
