This brass automatic air vent valve features a top vent cap and an external male threaded inlet connection.
The available product images also show an inlet screen positioned inside the threaded end.
Exact nominal size, pipe-thread standard, working pressure, working temperature and internal operating components are not confirmed by the currently available information and should therefore be checked before quotation.

Technical Buyer Notes
Top Vent Configuration
This version is distinguished by a vent-cap assembly positioned centrally on the upper cover.
Buyers replacing an existing air vent valve should compare the top configuration, connection size and installation dimensions before ordering.
Buyer Tip: this top-vent model should not automatically be treated as interchangeable with the side-vent version. Confirm the required configuration in the RFQ.
Male Threaded Connection
The valve uses an external male threaded inlet.
However, the product images do not confirm whether the thread is BSPP, BSPT, NPT or another pipe-thread standard.
The required thread specification should therefore be confirmed before quotation.
Inlet Screen
A screen is clearly visible inside the male threaded inlet in the current close-up image.
Screen material, mesh size and filtration specification are not confirmed and should not be assumed from appearance alone.
Confirm Pressure and Temperature
No confirmed PN, PSI or temperature marking is available in the current product information.
Working pressure and temperature should therefore be confirmed according to the actual piping-system requirement.
Automatic Air Vent Applications
Automatic air vent valves are used at points where accumulated air needs to be released from a piping system.
Final suitability should be evaluated according to the working medium, operating pressure, temperature and installation requirements.
