Product Description
Danfoss 157B Series PVG 32 Proportional Valve Components
Product Overview: The Danfoss 157B series is the cornerstone of hydraulic control for mobile machinery, primarily used within the PVG 32 proportional valve family. This series utilizes a highly modular design, allowing users to construct complex control logics by combining different work sections (e.g., 157B3171), electrical actuators (e.g., 157B4033), and end plates (e.g., 157B6200). With its superior Load Sensing performance, the 157B series ensures precise flow distribution across multiple simultaneous operations, making it the ideal choice for cranes, aerial lifts, and forestry equipment.
Featured models: 157B6200, 157B4034, 157B4032, 157B4033, 157B4735, 157B3171, and 157B3173.
Core Component Analysis:
PVE Electrical Actuators (157B4032/33/34): The central control units that drive the spool via proportional voltage signals, featuring integrated position feedback for high linearity and low hysteresis.
Basic Valve Modules (157B3171/73): Precision-machined cast iron bodies with pressure compensation, ensuring actuator speed depends solely on the control signal, independent of load pressure fluctuations.
PVS End Plates (157B6200): Responsible for merging hydraulic circuits and sealing the block, providing a stable system interface.
Environmental Resilience: Modules such as 157B4735 are engineered for extreme conditions, offering excellent vibration resistance and IP66/67 protection ratings.
