Tecofi air release valves
An automatic air release valve vents air that collects at high points of a closed pipework, preventing air locks that cut flow, cause noise and corrosion. Tecofi lists PU1100 chrome-plated brass (BSP male, 10 bar, up to +110°C), PVS4140S and PVS4150S ductile iron with BSP female threads (16 or 25 bar), and PVS4241A and PVS4251A ductile iron with PN10/16/25 flanges (25 bar), all with ABS floats on the iron models.

Where does an air release valve go?
At the highest point of a pipe run where air collects; add an isolating valve below it so it can be serviced without draining the system.
