Danfoss PVG 120 High-Flow Proportional Directional Valves

Product Overview: The Danfoss PVG 120 is a load-sensing proportional valve group engineered for heavy-duty mobile machinery demanding extreme flow and pressure capabilities. As the powerhouse of the PVG family, the PVG 120 series handles flow rates up to 240 L/min per section and operating pressures up to 400 bar. By integrating high-performance PVE actuators (such as 157B4028) with precision valve modules (such as 155G4284), this system provides unparalleled power and fine-metering control for mining equipment, large cranes, and drilling rigs.

Featured models: 155G4284, 157B4028, and related 155G & 157B series components.

Key Technical Advantages:

• Heavy-Duty Power Control: Optimized for high-power applications, capable of handling massive flow rates per section while minimizing pressure drop and maximizing energy efficiency.

• Load-Sensing Technology: Ensures precise flow distribution during simultaneous functions, independent of load pressure fluctuations for ultra-smooth operation.

• High-Response Electrical Actuation: PVE modules like the 157B4028 feature integrated closed-loop feedback, minimizing hysteresis and ensuring the spool follows commands with high fidelity.

• Rugged Modular Design: Constructed with high-strength materials to withstand the harshest mining and construction environments, supporting versatile spool configurations.

• Flexible System Integration: Compatible with electro-hydraulic, hydraulic, or manual control options, suitable for both open and closed-center hydraulic systems.
