Danfoss PVG Actuators & O-Series Hydraulic Motors

Product Overview: Danfoss offers industry-leading modular control and drive solutions for mobile hydraulic applications. This integrated page features core PVE electronic actuators for PVG proportional valves alongside high-performance Gerotor motors. Models like 157B4032 and 157B4035 represent the pinnacle of PVE digital control, enabling precise closed-loop positioning via electrical feedback. When paired with hydraulic motors such as the 151B3039 (OMSS) and 151G0034 (OMT), they provide smooth and powerful torque output for excavators, agricultural machinery, and forestry equipment.

Featured models: 157B4032, 157B4035, 151B3039, 151G0034, and the full range of 155G, 155L, and 152 components.

Key Technical Advantages:

• Digital Precision: 157B-series PVE actuators feature integrated LVDT sensors for real-time spool monitoring, reducing hysteresis to a minimum and ensuring seamless multi-function synchronization.

• Modular Flexibility: Components like 155G and 155L work sections allow for customized manifold builds (PVG 32/100/120) with full Load Sensing (LS) capabilities.

• Efficient Motor Drives: The 151B (OMS/OMSS) and 151G (OMT) motors utilize advanced disk valves and geroler gear sets to deliver high starting torque and superior volumetric efficiency.

• Extreme Durability: All components are engineered with high ingress protection (IP67) and vibration resistance, specifically tailored for harsh off-highway environments.

• System Compatibility: Electrical actuators support a wide 11V–32V input range, ensuring compatibility with diverse mobile machine electrical architectures.
