The Pratissoli PNRA2 automatic pressure regulator is a manually-adjustable, pressure-operated device which, according to its setting, limits the pump/system pressure by conveying the excess of water to the by-pass.

Moreover, when the outlet flow is blocked, this device totally releases the flow – and keeps under pressure the portion of the system following the valve, while it reduces the pressure in the portion of the system preceding the valve.
