Wilkerson Dial Air Regulator ½” NPT 300 Psi R21-04-000

Wilkerson Dial Air Regulator ½” NPT 300 Psi R21-04-000

Wilkerson dial air regulator systems offer unmatched precision and reliability for industrial pneumatic applications. If your facility relies on heavy-duty pneumatic systems to power industrial lifting equipment or manufacturing lines, the Wilkerson R21-04-000 Air Regulator is exactly what you need to maintain consistent air pressure. Designed for rugged environments, this premium wilkerson air regulator features a robust zinc body and operates flawlessly with a maximum supply pressure of 300 PSI (20.7 bar).

The defining feature of this wilkerson air pressure regulator is its transparent, pressure-calibrated, non-rising adjustment dial. Operators can effortlessly set secondary pressures ranging from 5 to 160 PSI in less than 270° of dial rotation, making it highly advantageous for applications where pressure must be changed frequently. Furthermore, this wilkerson r21 04 000 unit boasts a balanced valve design and is piston operated, ensuring high-relief flow and reliable performance across your entire airline.

How To Use:

Follow these standard operational steps for safe and effective compressed air regulation.

1. Preparation: Depressurize the air line completely before installing the wilkerson r21 into your pneumatic system.

2. Installation: Connect your 1/2″ supply line to the inlet port and the downstream equipment to the outlet port.

3. Mounting: Secure the unit in any desired position, ensuring the transparent dial face remains visible to operators.

4. Initial Adjustment: For best performance, regulated pressure should always be set by increasing the pressure up to the desired setting.

5. Dial Calibration: Turn the non-rising adjustment dial (less than 270° rotation required) to reach your target pressure between 5 to 160 PSI.

6. Gauge Setup: If monitoring is required, install a gauge into one of the two provided 1/4″ NPT gauge ports.

Warning:

Pay attention to these critical safety alerts to prevent pressure ruptures and equipment damage.

1. Over-Pressurization: Do not exceed the maximum primary supply pressure rating of 300 PSIG (20.7 bar).

2. Gas Restrictions: Product rupture can cause serious injury; do not connect this regulator to bottled gas.

3. Unintended Adjustments: The working range of the knob is designed to permit outlet pressures within their full range, but pressure adjustment beyond
   this range is possible because the knob is not a limiting device.

Precautions:

Keep these handling and maintenance guidelines in mind for long-term operational safety and peak control.

1. Temperature Limits: Do not operate the regulator outside of its safe operating temperature range of 32°F to 150°F (0°C to 65.5°C).

2. Air Bleed Awareness: Note that all Dial-Air units have a slight constant air bleed of 0.05 SCFM, which is normal for its balanced valve design.

3. Material Compatibility: Ensure that no incompatible synthetic compressor oils migrate into the unit, as they can attack the nitrile seals.

4. Visual Enhancements: The transparent dial can be color or graphics coded for easy reference to required pressure changes in your facility.
