Duplomatic Oleodinamica designs and produces a complete range of hydraulic components that are suitable for all application sectors of both industrial and mobile fields.

MZE valves are 3-way pilot operated pressure reducing proportional valves, designed as modular versions with mounting interface in compliance with ISO 4401 (CETOP RP121H) standards. The valves are used to reduce pressure in the secondary circuit branches thus ensuring stability of controlled pressure in the event of variations of the flow rate through the valve.

Pressure can be modulated continuously in proportion to the current supplied to the solenoid. The valve can be controlled directly by a current control supply unit or by an electronic control unit, to exploit valve performance to the full. The valve is available in three different pressure reduction ranges of up to 230 bar. The valve is available only with internal drain to the T line inside the valve.
