AVR Valve in Slurry Pipe 1

[rickfer]

Do anybody knows an Air-Vacuum Relief Valve that can work in a slurry pipe?

We have a 8"ø HDPE Pipe, with 450 gpm of slurry 45%-50% solids.

Pipe trajectory has being carefully traced, so we only have one high point, and no low points, and pumps motors have a VFD.

I belive we don't need an AVR Valve. beside, as it is slurry a regular AVR valve will be useless after few minutes of operation.
However, client insist.

Is your HDPE designed for full vacuum pressure? If so, skip the relief valve. If not design it for full vacuum, then skip the relief valve.

I agree with BigInch but if you must have one then look to the Ventomat RGx.

The danger is that the slurry will cake on the float. Then the AVR does not work.

AVR's are a device that the water industry oves but you dont see them in the petrochem, oil and gas, mining, power industries.
