1. Product Overview
The Walfront Brass Air Bleeder Valve Screw is a high-quality replacement component designed for use with high-pressure electric pumps. Constructed from durable brass, this valve offers strong wear resistance and is engineered to withstand high temperatures up to 300℃ and high pressures up to 65Mpa. Its primary function is to serve as a protective device, preventing components from excessive pressure buildup by allowing for controlled air bleed.
- Premium Quality Material: Made from high-quality brass for strong wear resistance and durability.
- High Temperature and Pressure Resistance: Designed to operate effectively under extreme conditions, up to 300℃ and 65Mpa.
- Essential for High-Pressure Air Pumps: Specifically used on high-pressure air pumps for efficient air bleeding.
- Protective Device: Acts as a safety mechanism to protect pump components from overpressure.

3. Components Included
Each package of the Walfront Brass Air Bleeder Valve Screw typically includes the following:
- 1 x Brass Air Bleed Valve (consisting of the screw and valve body)
This image shows the two main parts of the bleeder valve: the threaded valve body and the separate bleeder screw with its knurled head. This illustrates how the components fit together.
4. Setup and Installation
Proper installation of the bleeder valve is crucial for safe and effective operation. This valve is designed with a 10 x 1mm thread size. Ensure compatibility with your high-pressure electric pump before installation.
- Preparation: Before installation, ensure the receiving port on your high-pressure pump is clean and free of debris. Verify that the thread type is M10 x 1mm. Using an incorrect thread type (e.g., US tapered pipe thread) can cause damage and leaks.
- Thread Engagement: Carefully align the bleeder valve screw with the threaded port. Begin threading by hand to ensure it starts smoothly without cross-threading.
- Tightening: Once hand-tight, use an appropriate wrench on the hexagonal section of the valve body to gently tighten it. Apply firm but not excessive torque. Overtightening can damage the valve or the pump's port, potentially leading to component failure.
- Sealing: Ensure any included sealing washers or O-rings are properly seated before final tightening to create a secure, leak-free seal.

5. Operating Instructions
The Walfront Brass Air Bleeder Valve Screw functions as a pressure relief mechanism for high-pressure air pumps. It is designed to release excess air pressure safely and efficiently.
- Normal Operation: During the operation of your high-pressure electric pump, the bleeder valve remains closed, allowing pressure to build within the system.
- Releasing Pressure: To release pressure from the pump system, slowly turn the knurled cap of the bleeder valve counter-clockwise. Air will begin to escape, reducing the internal pressure.
- Closing the Valve: Once the desired pressure is reached or all excess air is bled, turn the knurled cap clockwise until it is finger-tight to close the valve and prevent air leakage. Do not overtighten.
- Safety Precaution: Always ensure the pump is not actively pressurizing when opening the bleeder valve, unless specifically instructed by your pump's manual for a controlled bleed procedure.

6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your Walfront Brass Air Bleeder Valve Screw.
- Cleaning: Periodically inspect the valve for any dirt, debris, or corrosion. Clean the exterior with a soft, dry cloth. Avoid abrasive cleaners that could damage the brass finish.
- Seal Inspection: Check the condition of any internal or external seals (e.g., O-rings, Teflon washers) if the valve is disassembled. Replace worn or damaged seals to prevent leaks.
- Thread Condition: Ensure the threads remain clean and undamaged. A small amount of appropriate thread lubricant (if recommended by your pump manufacturer) can be applied to ensure smooth operation and sealing.
- Storage: When not in use for extended periods, store the valve in a clean, dry environment to prevent oxidation or damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Air Leakage from Valve | Improperly tightened valve; Damaged or worn seals; Cross-threaded connection. | Ensure valve is tightened correctly (finger-tight for the cap, appropriate torque for the body). Inspect and replace seals if necessary. Re-thread carefully if cross-threading occurred. |
| Difficulty Threading Valve | Incorrect thread type; Damaged threads on valve or pump port; Debris in threads. | Verify thread compatibility (M10 x 1mm). Clean threads thoroughly. If threads are damaged, replacement may be necessary. |
| Valve Head Snapped Off | Excessive tightening torque applied during installation. | This indicates material stress failure. The valve must be replaced. Always use appropriate torque and avoid overtightening during installation. |
