Tamper-Resistant Compressed Air Regulators


Key Lock	Removable T-Handle	Knob-Locking Clip

Prevent unauthorized or accidental pressure changes to these regulators—they let you lock down the set pressure. Use these regulators to adjust and maintain the pressure of your compressed air. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.

Key Lock—Regulators with a key lock only let those with the key adjust the pressure. The lock is universal, so you can use the same key for multiple regulators.

Removable T-Handle—Regulators with a removable T-handle can only be adjusted when the handle is in place. Remove the T-handle to prevent further adjustments.

Knob-Locking Clip—Regulators with a knob-locking clip cannot be adjusted when the clip is installed between the knob and the body of the regulator. To adjust the pressure, remove the knob and clip, then reattach the knob.

Festo Modular Compressed Air Regulators

Set and hold the pressure of your compressed air. These regulators connect to other Festo units of the same series with joiner clamps (sold separately), so you can customize your air preparation system. They’re relieving, so they will exhaust when the downstream pressure exceeds the set pressure. Install these regulators on your air line after filters. To prevent unwanted pressure changes, slip a padlock through a hole in the knob.

Clean Room Precision Compressed Air Regulators

When precision and cleanliness are critical—such as semiconductor manufacturing and food processing—these regulators are cleaned and bagged in an ISO Class 3 clean room to prevent contamination. They deliver steady air pressure to generate precise, repeatable movement. A locking adjustment knob secures your settings to prevent accidental changes. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Compressed Air Regulators for Air-Powered Tools

Install these regulators directly on your air-powered tool to maintain the set air pressure.

Nonrelieving—Adjustable Outlet Pressure


Locking Collar with Screw Lock	Dial with Slide Lock

Nonrelieving regulators do not exhaust excess downstream pressure. These regulators are intermittent duty, so they’re ideal for tools that require short bursts of air, such as nailers, staplers, and small drills.

Pressure-Adjustment Dial—Regulators with a dial adjustment let you see the set pressure at a glance. Twist the dial to adjust the pressure, then slide the lock to prevent accidental changes as you use and jostle your tool.

Pressure-Adjustment Locking Collar—Regulators with a locking collar adjustment have a screw lock to prevent accidental changes to the set pressure as you use and jostle your tool. Turn the locking collar to adjust the pressure.

DIN-Mount Compressed Air Regulators

Mount these regulators to a 35 mm DIN rail with the included brackets. Use them to adjust and maintain the pressure of your compressed air. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. A padlock can be attached to the knob to prevent unauthorized changes to the pressure.

Electronically-Controlled Compressed Air Regulators with Display

Monitor and adjust compressed air pressure at the source and remotely. These regulators use an electronic pressure sensor and a color-changing display to give you instant feedback—green for in range, red for out of range, and yellow for errors. Set the pressure using the knob, display buttons, or connect them to your programmable logic control (PLC) via IO-Link. When connected to your industrial network, you’ll be able to change settings remotely, monitor performance, and run diagnostics. You’ll need an M8 connecting cable (sold separately) to link them to your network. Install these regulators in your air line after filters.

To prevent unauthorized or accidental changes, lock the knob with a padlock. You can also protect settings made on the display and PLC with a PIN code.

Precision Compressed Air Regulators

Use these regulators in sensitive applications that require constant, consistent pressure for precise force and movement. They’re often used on calibration stands in laboratories or with air-powered clamps that hold delicate items. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Regulating

Accuracy

BSPP Inlet Thread—BSPP threads are also known as G threads.

±0.1% Regulating Accuracy—Regulators with a ±0.1% accuracy have a sensor and a servo-adjustment mechanism that work together to monitor pressure and instantly adapt to input pressure changes—even when conditions change. They have a locking nut to prevent accidental pressure changes.

Mounting Brackets—Mounting brackets (sold separately) let you attach the regulator to a wall or equipment.
