3 Bar Pressure Relief Safety Valve - 1/2" F x F


Manufacturer: Generic

Product Information

3 bar (43.5 PSI) 1/2 inch BSP female x female pressure relief valve. Colour of plastic top may vary from picture (makes no difference to operation of valve).

Most closed type domestic central heating installations and equipment including combi systems are designed to operate at a pressure below 3 bar. To protect the equipment, including any radiators, a safety valve must be fitted to prevent pressure in the system exceeding 3 bar.

The outlet from a pressure relief valve should be positioned in a way so as to not scald people or animals with escaping hot water or steam.

BSP (British Standard Pipe Thread) sizes don’t match up with what you would measure using a ruler. Have a look at the BSPT link at the bottom of this page for more information about how plumbing threads are measured.
