PVG32 Hydraulic Multi-Way Valve
The PVG32 Hydraulic Multi-Way Valve, manufactured by Danfoss, is a high-performance hydraulic valve widely used in municipal vehicles, construction machinery, self-propelled agricultural vehicles, farming implements, drilling rigs, workover rigs, cranes, and construction equipment. Below is a detailed introduction to its features, applications, and technical specifications:
------
I. Technical Features
1. Modular Design
• The PVG32 adopts a modular design concept, allowing flexible combination into valve groups with different functions based on user requirements.
• Compact dimensions and lightweight construction facilitate easy installation and maintenance.
2. Load-Sensing and Flow Control
• The PVG32 is a load-sensitive hydraulic valve with load-independent flow control capabilities.
• Flow to each working module remains independent of load pressure, ensuring consistent actuator speeds under varying loads.
• Utilizespre-valve pressure compensationfor flow control, enabling seamless integration with fixed-displacement pumps to form a valve-controlled load-sensing hydraulic circuit. This improves flow control during valve spool movement.
• When paired with variable-displacement pumps, it forms apump-controlled load-sensing hydraulic circuit, matching pump output (pressure and flow) precisely to load demands, reducing energy waste.
3. Multiple Control Methods
• Supports various control modes, including manual, hydraulic, high-precisionPVE (Proportional Valve Electro-Hydraulic Control Module), and CAN bus control.
• The PVE control module offers advanced electronic control functions, enabling rapid response, high safety levels, and effective fault monitoring.
4. Energy Efficiency and High Performance
• Designed to minimize heat generation, enhancing operational efficiency and power density.
• Excellent speed regulation characteristics help reduce energy consumption, meeting challenges posed by new diesel engine emission regulations.
5. Diverse Functional Modules
• Integrates multiple functional modules, such ascushion valves, make-up valves, and secondary pressure-limiting valves, to meet diverse hydraulic system requirements.

II. Applications
1. Municipal Vehicles
• Used in refuse trucks, street sweepers, and other vehicles requiring simultaneous operation of multiple actuators with independent speed control.
2. Construction Machinery
• Ideal for excavators, loaders, and other equipment demanding precise control over actuator movement and speed.
3. Agricultural Vehicles
• Suitable for combine harvesters, tractors, and other farming implements needing adaptation to varying operating conditions and load changes.
4. Other Fields
• Applied in drilling rigs, workover rigs, cranes, and other equipment requiring high-performance hydraulic multi-way valves for stable operation.
