Air & Vacuum Release Valve
Air and vacuum release valves are critical pipeline components designed to automatically expel trapped air during system start-up and prevent damaging vacuum conditions upon shutdown or pipe drainage. Essential for maintaining hydraulic efficiency and protecting pipework integrity, these valves are widely used across irrigation, water distribution, and fluid management systems.

Air & Vacuum Release Valve Systems
Air and vacuum release valves play a crucial role in maintaining irrigation system efficiency by automatically venting air that can accumulate in pipelines and preventing damaging vacuum conditions. The collection features Bermad valves, including 1″ and 2″ combination units that handle both air release and vacuum relief functions, along with specialised automatic air release valves rated for 10 bar pressure. Vacuum breakers with BSP male connections provide additional protection against back-siphonage, whilst quick action pressure relief valves offer rapid response to pressure surges. These valves are designed for integration into irrigation systems where maintaining proper pressure and eliminating air pockets is essential for optimal water flow and system longevity.

Frequently Asked Questions about Air & Vacuum Release Valves
1. What is the purpose of an air and vacuum release valve in irrigation systems? Air and vacuum release valves automatically vent trapped air from irrigation pipelines during system filling and operation, whilst preventing vacuum formation that could damage pipes when the system is drained or experiences sudden pressure drops.
2. What’s the difference between a combination air and vacuum release valve and a standard air release valve? A combination valve performs both air release and vacuum relief functions in one unit, making it more versatile for complex irrigation systems, whilst a standard air release valve only vents air during normal operation.
3. Why do I need a vacuum breaker in my irrigation system? Vacuum breakers prevent back-siphonage and protect against vacuum conditions that could collapse pipes or draw contaminants into the system, particularly important in systems with elevation changes.
4. Are Bermad valves suitable for all irrigation applications? Bermad valves are designed for irrigation use and can handle pressures up to 10 bar, making them suitable for most residential and commercial irrigation systems, though specific requirements should be checked against system specifications.
5. How do I choose the right size air release valve for my system? Valve size should match your pipe diameter and system flow requirements – typically 1/2″ to 2″ for most irrigation applications, with larger systems requiring appropriately sized combination valves.
6. Will these valves work with my existing irrigation controller system? Air and vacuum release valves operate automatically based on pressure conditions and don’t require electrical connection to irrigation controllers, making them compatible with any system design.
7. What maintenance do air and vacuum release valves require? These valves require minimal maintenance but should be inspected periodically for debris or mineral buildup that could affect operation, with cleaning or replacement as needed.
8. Can I install these valves myself or do I need a professional? Installation typically involves standard pipe fittings and connections, though proper placement and system integration may benefit from professional installation to ensure optimal performance.
9. Why is there such a price difference between the vacuum breaker and pressure relief valve? The vacuum breaker is a simple mechanical device, whilst the quick action pressure relief valve incorporates sophisticated pressure-sensing mechanisms and rapid-response components, accounting for the significant price difference.
10. Are replacement parts available for these valves? Bermad valves typically have good parts availability through irrigation suppliers, though specific part availability should be confirmed with ILS Irrigation for your particular valve model.
