Providing a combination of high-flow performance, easy maintenance, and precise adjustment, ARO Fluid Pressure Regulators are recognized to be the premier regulators in the industry. Their reliable performance and innovative design features make them the preferred choice among fluid handling operators and material dispensing specialists.
The ARO I.D.L.® Fluid Regulator features smooth, consistent pressure regulation with easy-turn adjustment.
The removable plug allows quick access to the ball and seat of the fluid regulator. This 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.
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.
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.
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.
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.
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.
Back-pressure fluid regulators are typically used in recirculating or closed-loop systems, allowing them to maintain fluid pressure 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.
