How To Adjust The Working Pressure Of Fermenter

When the pressure in the fermenter reaches the working pressure, the safety valve will release the valve. Normally, the working pressure is fixed at 2 bar or 3 bar. sometimes, many customers want to adjust the working pressure. Therefore, this will involve three valves. Let’s compare these three safety valves together.

How To Adjust The Working Pressure Of Fermenter
How To Adjust The Working Pressure Of Fermenter

Picture 1 is a normal relief valve.
It is our standard configuration for fermenters and brewers. It cannot adjust the pressure. And it has a fixed maximum pressure value (usually 2 bar or 3 bar). Its maximum pressure is that it relieves not only positive pressure, but also negative pressure. Therefore, it is very necessary for water tanks.

Figure 2 shows the spigot valve. It has an adjustable pressure.
The advantages are

  1. it has a scale on the valve, so you can know the pressure you set.
  2. 2. You can observe the pressure of the relief valve. During its use, the white tray around the valve will be filled with water and when it starts to release pressure, we can see bubbles appear in the water. So, you can know exactly when the pressure is released.
    The disadvantage is.
    It does not work on negative pressure.
    A regular pressure relief valve (Figure 1) and a spigot valve (Figure 2) is a popular combination for customers who want to adjust the pressure.

Figure 3 is another type of adjustable pressure relief valve. Its pressure is also adjustable.
Pros: It can relieve both positive and negative pressures.
Disadvantages are

  1. It does not have a clear scale on the valve body.
  2. you can’t observe the pressure relief process like a bolt valve, 🙂
    In theory, this valve can replace the normal pressure relief valve. But for safer purpose, ordinary pressure relief valve is also necessary.

I hope my words can make you know more about the valves that can regulate the pressure of fermenter.
