Advantages
High Pressure/High FlowP, A, and B ports withstand 350 bar pressure, with a maximum flow rate of 80 l/min. The T port allows a back pressure of 210 bar, enabling direct installation in high-pressure systems without the need for an additional pressure-reducing circuit.
Soft Switching With Reduced ShockThe valve core features milled metering grooves and damping orifices, ensuring smooth switching, reducing hydraulic shock and noise, and extending the lifespan of the actuator and hoses.
High Power-To-Size RatioWet armature + aluminum valve body, compact size and light weight, saving approximately 15% more energy than comparable dry valves, suitable for space-constrained mobile equipment.
20 Million Cycle Life
Factory-tested fatigue life exceeds 20 million cycles, reducing downtime for maintenance and improving the main unit's OEE.
Quick Coil ReplacementDIN 43650 pluggable coil, replacement can be completed within 30 seconds without valve disassembly or oil draining, facilitating maintenance.
Multi-Fluid CompatibilityStandard Viton seals allow direct use with fire-retardant liquids such as mineral oil, water-glycol, and phosphate esters without the need for seal replacement.
Low Internal LeakageHigh-precision fit between the valve core and body ensures internal leakage ≤ 3 ml/min (70 bar differential pressure), improving load holding accuracy and reducing system temperature rise.
Rich Electrical OptionsMultiple coils available (24 VDC, 110 VAC, 220 VAC), with optional indicator lights, rectifiers, or junction boxes for easy PLC integration.
Applications
Construction MachineryPilot or main-stage reversing for multi-way valves in the traveling, steering, and working devices of excavators, loaders, and aerial work platforms.
Metallurgical EquipmentHigh-pressure, zero-leakage applications such as rolling mill balancing/bending rolls and continuous casting machine sector clamping.
Injection Molding/die Casting MachinesDirectional switching in 350 bar mold clamping hydraulic circuits; soft-switching function reduces mechanical shock and noise.
Test Benches And LaboratoriesFatigue testing benches requiring frequent reversals and high cycle counts. Marine and offshore applications: Hydraulic systems using fire-retardant fluids, such as steering gear, anchor winches, and hatch covers.
Agricultural Machinery
High-pressure circuits for hydraulic suspension systems of large tractors and header lifting systems of combine harvesters.
