The ZDE3G* series by Duplomatic are direct-operated proportional pressure reducing valves with on-board electronics (OBE), designed for subplate mounting in hydraulic systems. Here's a detailed breakdown:

 Specifications

• Mounting Interface: ISO 4401-03 (CETOP RP121H)
• Max Operating Pressure: 100 bar
• Max Flow Rate: 15 liters/minute
• Catalog Code: 81520
• Control Type: Open-loop proportional control

 Description

• These valves reduce pressure in secondary branches of hydraulic circuits.
• They maintain stable controlled pressure even with flow rate variations.
• Integrated digital amplifier simplifies installation and setup.
• Ideal for industrial automation, mobile hydraulics, and systems requiring precise pressure modulation.
