## Long description

The Automatic Air Vent Valve Afriso 3/8" Solar with Ball Valve 6b 150°C (77996) is a compact de-aeration device intended for solar thermal and heating circuits. It combines an automatic air vent with an integrated ball shut-off valve, allowing continuous removal of trapped air while enabling manual isolation when maintenance or replacement is needed. The unit is designed to withstand operating temperatures up to 150°C and is suitable for installation on collectors, solar loops and closed hydronic systems where reliable automatic venting improves circulation and system performance.
Advantages
The valve provides continuous automatic venting to reduce air pockets that can impair heat transfer and pump efficiency. Integration of a ball valve allows quick isolation of the vent without interrupting the rest of the circuit. The compact 3/8" connection and robust temperature rating make the device compatible with common solar and heating installations. Construction materials and design minimize leakage risks and support long-term, low-maintenance operation.
Suitable for
Solar thermal collectors and rooftop solar loops
Closed hydronic heating circuits
Heat exchangers and circulation circuits requiring automatic de-aeration
Systems where manual isolation of the vent is needed for maintenance
Key specifications
Connection size: 3/8"
Integrated shut-off: ball valve
Shut-off type designation: 6b
Maximum operating temperature: 150°C
Application: solar and heating circuits, closed hydronic systems
Function: automatic air venting with manual isolation
How to use
Install the automatic air vent valve vertically at a high point of the circuit where air accumulates, following the system manufacturer’s installation guidelines. Connect the 3/8" fitting securely into the designated port, ensuring compatible thread sealing and tightness. During normal operation the vent will open automatically to release trapped air; when maintenance or replacement is required, close the integrated ball valve to isolate the vent before removal. After service, reopen the ball valve and check for proper operation and absence of leaks.
Usage recommendations
Place the vent at the highest accessible point of the loop and verify compatibility with system fluids and maximum temperature. Periodically check the isolation valve for tightness and inspect for signs of leakage. If system contains aggressive fluids or additives, consult material compatibility data before installation.
