Danfoss PVG 32 Proportional Valves & PVEH Actuators

Product Overview:

The Danfoss PVG 32 is a highly flexible, load-sensing proportional valve system designed for heavy-duty hydraulic circuits ranging from construction machinery to forestry equipment. At its core, the system is driven by PVEH (High Performance) electro-hydraulic actuators, delivering exceptional precision in flow and pressure regulation. Supporting various control signals (Voltage, Current, or Bus control), the system ensures that complex mechanical operations are executed smoothly and accurately. By integrating load-sensing technology, the PVG 32 enhances maneuverability while significantly reducing energy loss.

Featured components include: PVEH32 high-performance actuators and part numbers 157B5111, 157B2000, 157B7004, 157B3171, 157B2320, and 11166775.

Key Technical Advantages:

• High-Performance Control: PVEH actuators (e.g., 157B5111) feature ultra-low hysteresis and high frequency response, maintaining dynamic consistency for boom or traction systems.

• Load-Sensing Technology: Automatically adjusts pump output to match load requirements, minimizing heat generation and maximizing system efficiency.

• Modular Versatility: The PVG 32 can be configured with relief valves, shock valves, and diverse pilot modules to accommodate complex hydraulic logic.

• Extreme Durability: Rated for high electrical protection (IP67), these components withstand intense vibration, extreme heat, and moisture in the toughest job sites.
