Pratissoli VP12 Foot Operated Distributor Valve. The Pratissoli VP12 unloading valve is a normally open pedal- operated device which, according to its setting, opens or closes the by-pass line. When the by-pass is open, the valve partially releases the flow, thus setting the system pressure to zero.

The control pedal allows to cut in (ON) or to cut out (OFF) the hydraulic pressure of the system. The control by pedal allows the Operator to work with both hands free and therefore to easily operate the lance or other devices, even when the working conditions are particularly difficult.
