The ZDE3G, ZDE3GL and ZDE3GH are proportional pressure reducing valves, direct operated, for subplate mounting. They 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.

The valve is available with different types of on-board electronics for open loop:

The G version is our standard electronics with analogue interface with current or voltage reference signal with connection 6 pin + PE.

The GL version comes with compact box with Io-Link, Can-Open or analog interface and 5 pin M12 connection.

The GH version has interface for fieldbus communication EtherCAT, Ethernet/IP, Profinet, PowerLink, with 11 pin M12 connection.
