The Pratissoli PNR4090 pressure regulator is a manually-adjustable, pressure-operated pneumatic-control device. According to its setting, this device limits the pump/system pressure by conveying the excess of water to the by-pass.

Moreover, when the outlet flow is blocked, it totally releases the flow, thus keeping the pump/system at the adjusted pressure.
