Small Air Release Valve for High Pressure Pump Station

Why Air Release Valves Are Essential in High Pressure Systems

• Pumps may lose efficiency or suffer cavitation damage.
• Pressure surges can stress fittings and joints.
• Flow rates become unstable, raising energy consumption.
• Long-term wear shortens equipment life and increases costs.

 A small air release valve provides continuous, automatic venting of micro air pockets, ensuring the system remains stable, safe, and efficient.

Key Requirements for High Pressure Pump Station Valves

 When specifying a small air release valve for high pressure applications, consider:

• Pressure Rating – Valves must withstand the station’s maximum operating pressure (often 16 bar, 25 bar, or higher).
• Robust Materials – Stainless steel or ductile iron with epoxy coatings are recommended for strength and corrosion resistance.
• Float and Seat Design – Precision components ensure reliable sealing under high pressure.
• Safety Features – Anti-slam or reinforced bodies may be required to handle rapid pressure changes.
• Maintenance Access – Pump stations often run continuously; valves should allow easy inspection and service.

Recommended Solutions

Stainless Steel Small Orifice Valves

• Excellent corrosion resistance.
• Suitable for aggressive or coastal environments.
• Designed for continuous duty under high pressure.

High-Pressure Ductile Iron Valves (Epoxy Coated)

• Cost-effective solution with strong structural integrity.
• Widely used in municipal pump stations.
• Long service life when coatings are maintained.

Combination Valves for Critical Systems

• Manage both large-volume air during filling and micro-air release during operation.
• Prevent vacuum conditions during shutdown or drain-down.
• Ideal for pump stations with long rising mains.

Installation Considerations

 For best performance in a high pressure pump station:

• Install valves downstream of pumps where air release is most critical.
• Use multiple valves at key points if the system has long rising mains.
• Ensure correct isolation and bypass arrangements for safe maintenance.
• Confirm compatibility with system design standards (e.g., AWWA, EN, ISO).

Summary

A small air release valve for a high pressure pump station is more than just a component — it’s a safeguard for pumps, pipelines, and the entire system.

 The right valve:

• Withstands high operating pressures.
• Automatically vents micro-air pockets.
• Extends pump life and reduces energy costs.
