OPV valve reinforced - with brass adjustment screw.
Details:
This is the overpressure valve or OPV for ascaso PID models. It reduces pump pressure from 15 bar to 9/10 bars
While designed for Fluidotech it may be possible to fit other pumps with the addition of fittings and thread locker
The pressure is adjusted with a screwdriver when assembled - anticlockwise for 10 bars. As the screw is now brass, adjustments can be more frequent than the plastic screw, which was designed for minimal use.
