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 ensures consistent pressure output and a wide pressure range. Models can be configured with different spring options for enhanced performance and improved regulator lifespan.
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 broad material compatibility. All regulator seals are made of PTFE for maximum chemical compatibility.
ARO’s industrial downstream regulator models feature a recessed hex-head fitting, allowing pressure adjustments with the included 3/8” wrench, which also removes the housing. The recessed screw helps prevent accidental or unauthorized adjustments.
Our industrial regulators can be opened for maintenance or inspection by removing four easily accessible hex-head screws. There’s no need to remove the regulator from the line during this process. The upper housing is made of corrosion-resistant zinc aluminum for a sleek appearance and long rust-free 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.
