 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.  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.  TAMPER-RESISTANT SPRING ADJUST ARO’s industrial downstream regulator models have a recessed...

Typical Applications Dead End System Filter Downstream Regulator Downstream Regulator SUPPLY PRESSURE REGULATED PRESSURE RETURN Selecting the Right Regulator Position Model Number Example HIGH OR LOW PRESSURE ARO industrial fluid regulators can be divided into two types – Low Pressure and High Pressure. Low Pressure models are capable of regulated pressures of 800 psi or less. High Pressure models can regulate pressure in excess of 800 psi. DOWNSTREAM OR FLOW (PORT & BALL SIZE) BACK-PRESSURE ARO industrial fluid regulators are divided Different applications require different into Low Pressure...

Recirculating System 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.
