Backflow valve for screw compressors
2 screw compressors combined 1(30hp)other 1(50hp)each have a tank.
I'm a little confused to why a backflow valve is needed?
30hp is main one used, 50hp is backup.
Pressure is set on 30hp to cut-in 100psi cut-out 125psi.
Pressure is set on 50hp to cut-in 90psi cut-out 125psi.
