The A11VO190-260 LRDH2 Hydraulic Valve is a component specifically designed for use in certain hydraulic systems, often in conjunction with Rexroth's A11VO series of variable displacement piston pumps. Here is a detailed breakdown of this hydraulic valve:
I. Basic Overview
• Model: A11VO190-260 LRDH2
• Type: Hydraulic Valve
• Compatibility: Primarily designed for use with Rexroth's A11VO series hydraulic pumps (such as A11VO190, A11VO260, etc.).
II. Functional Characteristics
• This hydraulic valve may feature functions such as pressure cutoff, constant power control, and variable displacement control, which help regulate and stabilize the pressure, flow rate, and power of the hydraulic system.
• The pressure cutoff function automatically reduces the pump's displacement when the system pressure reaches a preset value, protecting the system from excessive pressure damage.
• The constant power control function ensures that the hydraulic pump does not exceed the predetermined driving power at a constant driving speed, maintaining stable system operation.
III. Application Fields
• The A11VO190-260 LRDH2 Hydraulic Valve is primarily used in the field of engineering machinery, such as concrete pump trucks, shovels, road construction machinery, etc. These machines typically require high-performance, reliable hydraulic systems to support their complex operational processes.
IV. Technical Specifications and Parameters
• Specific technical specifications and parameters may vary depending on the manufacturer and product batch. Key indicators typically include working pressure, flow rate, displacement, and control methods.
• When selecting and using this valve, it is important to refer to the technical manuals and specification sheets provided by the manufacturer to ensure compatibility and matching between the selected hydraulic valve, hydraulic pump, and other system components.
V. Precautions
• When installing and using the A11VO190-260 LRDH2 Hydraulic Valve, strict adherence to the manufacturer's installation guidelines and operating manuals is essential to ensure proper installation and safe operation of the system.
• Regular maintenance and inspections of the hydraulic system, including cleaning, checking, and replacing the hydraulic valve, are necessary to extend system life and maintain stable performance.
In summary, the A11VO190-260 LRDH2 Hydraulic Valve is a high-performance, multifunctional hydraulic component suitable for fields requiring high-precision and high-reliability hydraulic systems, such as engineering machinery. When selecting and using this valve, it is important to consider factors such as technical specifications, functional characteristics, and application fields.
