OPV valve reinforced - with brass adjustment screw. New for 2022


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 10bars. As the screw is now brass, adjustments can be more frequent than the plastic screw , which was designed for minimal use.


Technical specifications:

Material: Brass body and brass adjustment screw

Size:1/8 female (Boiler side) x 12x1mm female (Pump side) + 7mm (Silicon hose outlet )
