Automatic Air Vent Valve, G1/2 DN15

Help a compatible heating or water circuit release accumulated air with this automatic vent valve. Its compact body combines a threaded connection and top vent assembly, providing a dedicated air-release point in the system.

Release trapped air from a compatible water circuit

• ✅ Vent accumulated air automatically — the valve is intended to release trapped air from the connected circuit.
• ✅ Match a defined connection size — the G1/2 DN15 connection gives you a clear starting point when checking your system’s fittings.
• ✅ Keep the vent assembly accessible — the top cap and removable body sections allow access for servicing according to the valve instructions.
