Fluid supply valves open and pressure set
The recommended component A and B fluid supply pressures are 1/2 to 2/3 of the target spray pressure.
NOTE: Low pressure systems may be set within a range of ± 100 psi (0.7 MPa, 7 bar); high pressure systems may be set within a range of ± 300 psi (2.1 MPa, 21 bar). If the inlet pressure is higher than the outlet pressure, ratio accuracy may be affected.
Solenoid pressure set
