Genuine Reliance PREL102042 6 Bar 102 Series Relief Valve 1/2" M x F BSP
102 Series potable water relief valve, pre-set and locked at 6 bar, with a 1/2 inch BSP male inlet and female outlet. The cartridge lifts out for cleaning or replacement.
What it does
Water expands as it heats. An expansion relief valve opens at its set pressure and releases the excess to the tundish, so the system never runs above its design pressure. A relief valve that drips continually is a common sign it needs replacing.
Where it fits
Unvented hot water cylinders and sealed water systems - the expansion relief valve that discharges excess pressure at its set point.
