Overview Rexroth cartridge valves

Compact and flexible in design, Bosch Rexroth valves are incredibly versatile and adaptable to a wide range of hydraulic systems.

Components of a Cartridge valves

A standard Bosch Rexroth cartridge valve is made up of a few essential parts.

• Housing: This is the main body of the valve, providing structural support and a mounting interface for other components. It's usually made of a high-strength material like steel or cast iron.
• Cartridge: This is the functional heart of the valve. It's a self-contained unit that houses the internal hydraulic components responsible for controlling fluid flow. Cartridges are typically interchangeable, allowing for easy customization and maintenance.
• Spool or Piston: This is the component that moves inside the cartridge to regulate the hydraulic fluid's flow path. Depending on the particular function of the valve, the design might be either spool- or piston-type.
• Spring: This part ensures that the valve returns to its neutral position when the actuating force is released by providing a force against the spool or piston.

Basic Operation Principle Cartridge Valves

The basic but efficient mechanism behind how Rexroth cartridge valves work is controlling the flow of fluid through a number of internal passageways. This flow is controlled by the main parts of a cartridge valve, such as the piston or spool.

Via an inlet port, hydraulic fluid enters the valve. A force from outside the cartridge, like a solenoid or lever, moves the spool or piston. This movement modifies the fluid's flow path, which may lead to fluid diversion, fluid flow, or fluid blockage. A spring makes sure that the valve returns to its default state by returning the spool or piston to its neutral position when the external force is released.

The specific flow control functions of a valve are determined by the shape and configuration of its spool or piston, and its sensitivity is influenced by the force necessary to move it. On the other hand, the tension of the spring influences this force. O-ring seals provide the smooth operation of the valve and stop fluid leaks. If applicable, pilot valves can be used to operate the main valve in order to add features or functionality.

Understanding the basic working concept of Rexroth cartridge valves will help you better understand their versatility and efficacy in a range of industrial applications.

Types of Bosch Rexroth Cartridge Valves

Numerous cartridge valves are available from Bosch Rexroth, each of which is intended to carry out a particular task in hydraulic systems. Here are some of the most common types:

Rexroth directional valve

• Two-way valves: The fluid flow between two ports is regulated by these valves. The fluid flow can be started, stopped, or reversed with them.
• Three-way valves: The fluid flow between three ports is managed by these valves. They can be employed to route fluid to various hydraulic system components.
• Four-way valves: The fluid flow between the four ports is managed by these valves. In a hydraulic system, they can be utilized to regulate the fluid's flow rate and direction.

Rexroth pressure control valve

• Rexroth pressure relief valve: These valves are employed in hydraulic systems to restrict the maximum pressure. The valve opens to release pressure when the pressure reaches a preset level.
• Rexroth pressure reducing valves: These valves lower the fluid's pressure as it passes through a hydraulic system. They can be employed to shield components further downstream from high pressure.
• Rexroth pressure intensifiers: The fluid passing through a hydraulic system can have its pressure increased with the use of these valves. Tools or high-pressure hydraulic cylinders can be powered by them.

Flow Control Valves

• Fixed flow control valves: The purpose of these valves is to keep the flow rate via a hydraulic system constant. They can be applied to regulate the speed of hydraulic cylinders or motors.
• Variable flow control valves: The hydraulic system's flow rate can be adjusted with the use of these valves. They can be employed to manage the pressure in a hydraulic system or to control the speed of hydraulic cylinders or motors.

Check Valves

• Spring-loaded check valves: The purpose of these valves is to stop fluid from returning to a reservoir or pump. When the flow direction changes, a spring-loaded poppet on them closes.
• Pilot-operated check valves: These valves are employed in hydraulic systems to regulate fluid flow. The main bosch valve can be opened or closed using a pilot valve that they have.

Sequence Valves

• Pressure sequence valves: These valves regulate the order in which hydraulic system operations occur. They can be used to make sure that particular parts or features are turned on in a particular order.
• Time sequence valves: These valves are used to regulate a hydraulic system's time-based operation sequence. They can be applied to postpone the activation of specific parts or features.

Other Types of Cartridge Valves

• Pilot-operated valves: These valves work with a small pilot bosch valve to regulate the fluid flow in a hydraulic system.
• Proportional valves: These valves regulate a hydraulic system's fluid flow in response to an electronic signal.
• Servo valves: These valves are used to quickly and precisely regulate the fluid flow in a hydraulic system.

Your hydraulic system's specifications will determine the precise kind of valve you require.
