In these applications, this DAV10 Single Orifice Air Release Valve ensures precise fluid control, maintains excellent sealing integrity, and supports efficient, safe operation even under demanding conditions.
The DAV10 Single Orifice Air Release Valve is an essential, high-reliability component engineered specifically for the continuous automatic discharge of accumulated air from pressurized water pipelines and process vessels. Designed to meet the stringent demands of modern infrastructure, this specialized valve ensures peak operational reliability and long-term durability by preventing air pockets that cause flow restrictions, inaccurate metering, and pressure spikes.
At the core of the DAV10 Single Orifice Air Release Valve is its simple, lever-and-float mechanism. When air accumulates inside the valve chamber, the internal float drops, opening a small orifice to release the trapped air at system pressure. As fluid enters the chamber, the float rises, sealing the orifice completely. This precise, small-volume air discharge prevents air binding, ensuring smooth and efficient fluid transfer throughout the network.
Manufactured from high-strength, corrosion-resistant materials and built with a robust body, the DAV10 Single Orifice Air Release Valve is designed to withstand continuous system pressure and challenging operating environments. Its compact, simple design allows for secure installation at high points in the piping system. The reliance on buoyant force for operation guarantees reliable, automatic air removal, which significantly maintains the hydraulic integrity and capacity of the pipeline.
The DAV10 Single Orifice Air Release Valve is ideally suited for applications in municipal water distribution mains, filtration plant manifolds, sewage force mains (for air, not solids), and any high-point in a pipeline where continuous venting of dissolved and accumulated air is essential. Its reliable function makes it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term pipeline efficiency and maintenance reduction.
In summary, the DAV10 Single Orifice Air Release Valve offers an optimal combination of automatic venting performance, durability, and hydraulic efficiency. With its proven float mechanism, simple construction, and focus on continuous air removal, this unit stands as a trusted solution for modern fluid control and pipeline protection requirements worldwide.
1. General Information
The DAV10 Single Orifice Air Release Valve is designed for the continuous removal of small volumes of air from pressurized systems. Proper installation is essential to guarantee safe operation, long service life, and sustained hydraulic efficiency.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with pressurized pipelines.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and isolated before attempting to install the DAV10 Single Orifice Air Release Valve.
3. Pre-Installation Checklist
Inspect the DAV10 Single Orifice Air Release Valve for any visible damage during transport or storage, paying attention to the float mechanism and seals.
Check that the valve type, size, and pressure rating match the system requirements.
Verify that the valve interior is clean and free from debris that could interfere with float movement or sealing.
Confirm that the mating pipe connection (e.g., flange or thread) is clean and properly aligned. Ensure sufficient space is available above the valve for vertical installation and future maintenance access.
4. Installation Procedure
Positioning: Install the DAV10 Single Orifice Air Release Valve vertically, generally at the highest points of the pipeline profile, where air naturally collects. The valve must be installed with the inlet facing upward to ensure the float operates correctly.
Use the appropriate sealing materials (e.g., gaskets, thread sealant) suitable for the medium and operating conditions.
Align the valve precisely with the pipe connection and secure it firmly. Avoid overtightening threaded connections, which could damage the valve body.
5. Post-Installation
Slowly reintroduce fluid and pressurize the system, allowing air to escape through the open orifice. Monitor the valve to ensure the float rises and seals the orifice completely once the liquid fills the chamber. Record the installation details, date, and final notes for documentation purposes.
Proper maintenance extends the service life of the DAV10 Single Orifice Air Release Valve and ensures reliable air discharge and system protection. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DAV10 Single Orifice Air Release Valve exterior regularly (e.g., monthly) for signs of external leakage from the orifice or connection points. Listen for any continuous hissing sound during operation, which may indicate a failed seal or a foreign object preventing the float from seating properly.
2. Inspection Schedule
Monthly, check the area surrounding the valve for any signs of fluid spray or leakage.
Quarterly, check the cleanliness of the valve inlet passage to ensure no fouling is restricting air or water flow into the chamber.
Annually, perform an internal inspection by removing the cover to check the condition of the float, lever mechanism, and orifice seal.
3. Lubrication
The internal components and float mechanism of the DAV10 Single Orifice Air Release Valve operate freely within the fluid and are generally designed to be maintenance-free. No external lubrication is required for the internal components.
4. Seal and Gasket Replacement
Replace the cover gasket and orifice seal immediately if persistent external or internal leakage is observed. The internal float mechanism should only be replaced if the valve fails to seal completely (constant leakage) or fails to open (air binding occurs). Always isolate the valve and depressurize the section of the pipeline thoroughly before attempting any maintenance work requiring cover removal.
5. Cleaning
Keep the exterior of the DAV10 Single Orifice Air Release Valve clean to prevent surface corrosion. The small orifice hole may require occasional cleaning to ensure no particles block the air exit path.
6. Storage and Spare Parts
Store spare parts (gaskets, orifice pins, floats) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes. Maintain a detailed record of all inspections, internal part replacements, and repairs performed on the DAV10 Single Orifice Air Release Valve unit.

Frequently Asked Questions about the DAV10?
What are the main advantages of this valve?
The DAV10 Single Orifice Air Release Valve offers continuous, automatic discharge of small air pockets at system pressure, which is vital for maintaining hydraulic efficiency, preventing air binding, and ensuring accurate flow metering in pressurized pipelines.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What is the primary function of the single orifice in the DAV10 Single Orifice Air Release Valve?
The small, single orifice is specifically designed to continuously release small amounts of trapped air under pressure, ensuring that the air is vented before it can accumulate and negatively impact pipeline flow and efficiency.
Can this valve be used for discharging large volumes of air, such as during pipe filling?
No. The DAV10 Single Orifice Air Release Valve is designed for the slow, continuous venting of air under pressure. Discharging large air volumes requires a combination (double orifice) valve or a large orifice valve.
What is 'air binding' and how does the DAV10 Single Orifice Air Release Valve prevent it?
Air binding is the accumulation of air pockets at high points in a pipeline, which restricts flow and increases pumping head. The DAV10 Single Orifice Air Release Valve prevents this by automatically venting these pockets as soon as they form, maintaining the pipeline’s full capacity.
