foam storage tank

Thread Content

Our company has installed a foam fire pump station, in which a pressure-maintaining and pressure-relieving valve is installed between the pump outlet and the foam storage tank proportional mixer inlet. What is the function of this pressure-maintaining and pressure-relieving valve? Why is this valve installed?

The function of the pressure maintaining valve is to ensure that the pressure of the foam solution entering the proportional mixer is within the set pressure range. This will allow the proportional mixer to work properly.
