Rated 5 out of 5 by from Pressure release valve Very good value for money and does exactly what its meant to. My only moan is that I ordered it on the Sunday and it was due on the Wednesday but DPD did not deliver it on their rounds and I was not informed and had to go back on the Thursday to collect. Apart from that the process was very smooth.

What is the relief pressure for this valve.

Asked by: MJA95
The pressure is preset to 6 bar as marked on the knob. It CAN NOT be adjusted. Turning the knob moves it up a ramp and it will release system pressure to the tundish. Once the ramp is overrun it snaps back shut. If it is not fully seated but left on the ramp the valve seat will be eroded, it will leak and need replacing.
