Vickers Proportional Valve PA5DG4S4LW-0133C-H-60-S471 Blue High Reliability Cast

Product Specification

Description:

The Vickers Proportional Valve PA5DG4S4LW-0133C-H-60-S471 is a high-performance proportional directional valve manufactured by Vickers (now a brand under Eaton). This valve features a pilot-operated design, enabling precise control of hydraulic oil flow direction and volume via electrical signals. It is suitable for hydraulic systems in various industrial and engineering machinery applications. This valve is a proportional directional valve with pilot control functionality. The electrical connection is a 24V DC power supply. The rated flow rate is 60 L/min. The valve receives electrical signals via an electromagnetic coil, controlling the movement of the pilot valve spool, which in turn drives the main valve spool to achieve continuous regulation of hydraulic oil flow direction and flow rate. This design enables the valve to achieve high-precision proportional control.
 

Application areas:

Industrial automation: In industrial automation systems, the Vickers Proportional Valve PA5DG4S4LW-0133C-H-60-S471 can be used to control the displacement, speed, and force of hydraulic cylinders, enabling programmable control of complex movements. For example, in automated assembly lines, stamping equipment, injection molding machines, and other systems, this valve ensures smooth operation and rapid response.
Construction machinery: In construction equipment such as excavators, cranes, and concrete pump trucks, this valve is used to control the movements of hydraulic motors and cylinders, enabling precise operations. For example, in crane boom extension control, the proportional valve can precisely control the extension speed of the cylinder based on input signals from the control lever, enhancing operational safety and efficiency.
Metallurgy and heavy machinery: In heavy equipment such as steel mills, rolling mills, and presses, this valve can be used to control high-pressure hydraulic systems, enabling precise control of heavy-duty equipment. Its high pressure resistance and stability make it suitable for extreme operating conditions.
Testing and Simulation Equipment: In systems with high dynamic response requirements, such as hydraulic test stands, flight simulators, and automotive testing equipment, this valve provides high-frequency, high-precision hydraulic control to meet complex testing needs.
 

Advantages:

High-precision control: This proportional valve employs electro-hydraulic proportional control technology to achieve continuous, stepless regulation of hydraulic system flow and direction. Compared to traditional on/off directional control valves, it eliminates hydraulic shock and uneven operation issues, significantly improving system control precision and stability.
Fast response speed: Due to its pilot-controlled structure, this valve has a fast response speed, making it suitable for applications requiring frequent start/stop operations or rapid directional changes. Its dynamic response characteristics meet high-frequency control requirements, enhancing overall system efficiency.
Energy-efficient and high-performance: By precisely controlling fluid flow, this valve minimizes unnecessary energy loss. For example, under low-load conditions, the system automatically reduces flow output to reduce energy waste, enabling energy-efficient operation.
High reliability: Vickers proportional valves are made of high-quality materials and advanced manufacturing processes, offering excellent wear resistance and contamination resistance. Their rational structural design ensures easy maintenance, a long service life, and suitability for long-term continuous operation.
Compatibility and modularity: This valve can be seamlessly integrated with Vickers amplifiers, sensors, controllers, and other components to build a complete electro-hydraulic proportional control system. Additionally, its modular design facilitates system expansion and maintenance.
