DV is a dosing valve, composed of two intercepting elements. The butterfly is suitable to execute a rough dosing while the small rotor carries out a fine dosing. The maximum accuracy achievable is +/- 20 grams, the valve can be interfaced with dosing and weighing systems. The Double Valve can be supplied with a sealing gasket between the vane and the dosing rotor (DVG). This solution allows the valve to work in applications with pressure up to 0,5 bar. The overall dimensions of the valve remain the same.
