ARO I.D.L.® Fluid Pressure Regulators
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.
Description
- Multiple materials of construction
- Standard / High capacity options
- Floating seat design
- Remote models
- Pressure gauge and riser tube included
- “Easy-flush” mode
Typical Applications
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.
Fluid Regulator Features
Easy-access Seat Plug
Removable seat plug allows for quick access to the ball and seat of the fluid regulator for immediate seat access. The feature reduces downtime for cleaning or replacing the seat, if needed. It also allows users to switch to different ball and seat sizes to achieve different flow rates.
Larger Adjustment Spring
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.
Tamper-resistant Spring Adjust
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.
Dual Diaphragm
ARO industrial fluid regulators utilize a diaphragm-to- ball check design. This dual diaphragm arrangement stands up to abrasive materials, prevents “caking” and allows for easier flushing. The diaphragm-to-seat ratio allows for consistent regulator performance, where pump “trip-over” and multiple application demands exist.
“Floating” Seat and Ball Arrangement
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.
Smooth-Turn Needle Bearing
A needle bearing has been incorporated to permit a smoother, easier adjustment – rather than relying on just spring adjustment – and can even be done while the regulator is on-line and operating.
“Easy-Flush” Mode
ARO’s industrial downstream regulator models have a unique flush-out mode, where by simply turning a key (provided) clockwise, the entire center spindle moves downward, forcing the ball off the seat and purging the entire regulator of particle build-up.
Base Housing Material Choices
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.
Easy-Access Housing Fasteners
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.
