2PCS Kinetic Release Air Valve – 3/4" BSP/NPT Male Thread for Drip Irrigation Systems

Keep your agricultural or garden drip irrigation system running at peak efficiency with this set of 2 Kinetic Release Air Valves. Designed with a 3/4" BSP/NPT male thread, these valves automatically vent trapped air from your irrigation lines — preventing airlocks, water hammer, and flow disruption so your crops and plants always receive consistent, even water distribution.

Why Air Release Valves Matter

Air pockets in pressurized irrigation lines reduce flow rate, cause uneven watering, and can stress pipe fittings over time. These kinetic air relief valves expel air automatically during system start-up and operation, ensuring smooth, uninterrupted water delivery across your drip network.

Frequently Asked Questions

Q: Are these air release valves compatible with both BSP and NPT fittings?

A: Yes! These kinetic air release valves feature a 3/4" male thread that is compatible with both BSP (British Standard Pipe) and NPT (National Pipe Thread) fittings, making them suitable for a wide range of drip irrigation systems and connectors.

Q: What is the maximum pressure these valves can handle?

A: These air relief valves are rated for a working pressure of 0.1 to 10 Bar, with a maximum pressure of 850 kPa. This covers the pressure range of most residential and agricultural drip irrigation systems.

Q: Can I use these valves outdoors year-round?

A: The PP body and EPDM seal are designed for outdoor use and can operate in temperatures from 1°C to 60°C. For regions with freezing winters, it is recommended to drain and store the valves when temperatures drop below 1°C to prolong their lifespan.

Q: Where should I install these air release valves in my irrigation system?

A: Air release valves should be installed at the highest points in your irrigation pipework, where air naturally accumulates. Installing them at these locations ensures trapped air is efficiently vented, maintaining consistent water flow and pressure throughout your drip system.
