Choose by air-preparation job

Start with the air quality or pressure job.

Pick the closest FRL use case, then confirm port size, flow, pressure range, filtration, drain, bowl, gauge, and service access before RFQ.

Scenario 01

Set stable working pressure for a pneumatic machine branch.

Confirm inlet pressure, outlet target, and flow demand before selecting regulator size.

Recommended option

Pressure regulator matched by adjustment range, port size, flow, and gauge requirement.

Inlet pressure
Outlet target
Rated flow
Port size

Common FRL uses

Where air preparation units protect the pneumatic line.

XAR 8000-9000 Series High-Flow Pneumatic Pressure Regulator product image

FRL use 01

Cylinder force and clamp control

Use pressure regulators to set actuator force for clamps, presses, stoppers, and fixture motions where pressure directly affects holding or pushing force.

Confirm outlet target
Check flow demand
Keep the gauge readable

XGR Series Pneumatic Pressure Regulator (XG Line) product image

FRL use 02

Blow-off and air-tool pressure branches

Use regulators to limit branch pressure for air blow guns, nozzles, tools, or operator workstations so the air point runs within the required range.

Set pressure range
Match port size
Review downstream demand

XGFR Series Pneumatic Filter Regulator Unit (XG Line) product image

FRL use 03

Precision test or inspection points

Use precision regulators where inspection, leak-test, gripping, or sensitive pneumatic functions need tighter outlet-pressure stability than a standard regulator.

Define pressure tolerance
Check response need
Protect adjustment access

Compressed-air tools

Review pressure stability and air capacity before selecting FRL units.

Pair filters, regulators, lubricators, and complete FRL units with pressure-drop, compressor, receiver, and pressure-unit checks.

Category FAQ

Common questions before sending an inquiry.

01Pneumatic Pressure RegulatorsWhat should I send for a pressure regulator quote?

Send inlet pressure, outlet pressure target, flow requirement, port size, gauge/bracket needs, material preference, environment, and old model photos if replacing a unit.

02Pneumatic Pressure RegulatorsWhen is a precision regulator needed?

Use a precision regulator when the application needs tighter outlet-pressure stability than a standard line regulator can provide.
