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.
| Model | Body material | Connection | Max pressure | Max temperature |
|---|---|---|---|---|
| PU1100 | Chrome-plated brass; brass float | BSP male | 10 bar | +110°C |
| PVS4140S / PVS4150S | Ductile iron EN-GJS-400-15; ABS float | BSP female | 16 or 25 bar | +80°C |
| PVS4241A / PVS4251A | Ductile iron EN-GJS-500-7; ABS float | PN10/16/25 flanged | 25 bar | +80°C |
Brands listed here: Tecofi. CAD sends datasheets, size tables and CO/CQ and advises on the model by pressure and connection type.

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.
What do you need for a quote?
Working pressure, temperature, connection type (threaded or flanged) and size.
Frequently asked questions
What is an air release valve for?
An automatic air release valve vents air that collects at the high points of a closed pipeline. This prevents air locks that reduce flow, cause noise and lead to corrosion in water and HVAC systems. Tecofi offers brass and ductile iron versions with threaded or flanged ends, up to 25 bar.
Which air release valve models does Tecofi offer?
Tecofi offers the PU1100 in chrome-plated brass with male BSP thread; the PVS4140S and PVS4150S in ductile iron with female BSP thread; and the PVS4241A and PVS4251A in ductile iron with PN10/16/25 flanges. The ductile iron models use an ABS float.
What maximum pressure and temperature do Tecofi air release valves handle?
Per the datasheets, the PU1100 is rated 10 bar and up to +110°C. The PVS4140S/4150S are rated 16 or 25 bar and the PVS4241A/4251A 25 bar, all with a maximum temperature of +80°C. Choose the model by working pressure and connection type.
Where can I buy genuine Tecofi air release valves?
You can buy genuine Tecofi air release valves from CAD. CAD sends the datasheet, dimension table and CO/CQ, helps you choose a model for water and HVAC pipelines, and quotes within 24 working hours when you send a request on the contact page.
