Pressure valves from the Bosch Rexroth manufacturer are key components in hydraulic systems. They provide control and regulation of fluid pressure to maintain safe and efficient system operation. Bosch Rexroth pressure valves are designed to prevent overpressure levels, protect system components from damage and ensure stable operating pressure.
The principle of operation of such devices is that initially, you set the maximum pressure, above which the valve begins to open. This set pressure can be adjusted using an adjusting screw or a special mechanism on the valve. When system pressure exceeds a set limit, hydraulic fluid begins to force against the piston or diaphragm inside the valve. This pressure creates a force that overcomes the force of the spring that holds the valve closed.
Once the force from fluid pressure exceeds the force of the spring, the valve opens, allowing some of the fluid to flow into the relief line or back into the reservoir, thereby reducing the system pressure to the set level. When the system pressure drops below a preset limit, the spring returns the piston or diaphragm to its original position, closing the valve and stopping fluid discharge.
Types of Bosch Rexroth Pressure Valve
Bosch Rexroth offers a wide range of pressure valves that provide reliable and precise pressure control in hydraulic systems. These valves are designed for system protection, maintaining stable pressure, and ensuring safe operation. Let's look at the main types of Bosch Rexroth pressure valves.
Mechanical pressure relief valves
Mechanical relief valves relieve excess system pressure, preventing damage and ensuring safe operation. They automatically open when a preset pressure is reached and return to the closed position when the pressure drops to a safe level.
Proportional pressure relief valves
Proportional safety valves provide more precise and smooth pressure control. They are controlled by an electrical signal, which allows you to flexibly change the set pressure values depending on operating conditions.
Mechanical pressure reduction valves
Mechanical pressure reducing valves reduce fluid pressure to a certain level necessary for the operation of individual system components. They maintain a stable outlet pressure regardless of changes in inlet pressure.
Proportional pressure reducing valves
Proportional pressure reducing valves provide precise and smooth pressure reduction using an electrical signal. This allows for more flexible pressure adjustment depending on system requirements.
Pressure reducing and relieving valves
Pressure reduction and relief valves perform two functions: they do pressure limiting to a predetermined level and relieve excess pressure, preventing overload of the system. These valves ensure stable system operation under changing conditions.
Pressure sequence valves
Sequential pressure valves control the sequence of operations in a hydraulic system, opening when a certain pressure is reached. They ensure the correct order of operation of the various components of the system.
Pressure cut off valves
Pressure cut off valves automatically stop fluid flow when a set pressure is reached. This protects the system from overloads and prevents equipment damage.
Pressure compensators
Pressure compensators maintain constant system pressure to compensate for load changes. They ensure the stable operation of the system and prevent pressure spikes.
Pump safety blocks
Pump safety units include safety valves and other devices to protect pumps from overpressure and overload. They ensure the safe and reliable operation of pumping stations.

How to Choose the Right Bosch Rexroth Pressure Valve
Selecting the correct pressure valve is an important step in ensuring reliable and efficient hydraulic system operation. So let's look at the criteria that you should consider to buy Bosch Rexroth pressure valves that meet your needs.
- Determine the operating pressure of the system. Ensure that the valve's maximum operating pressure exceeds or meets your hydraulic system requirements to ensure safe operation.
- Consider the type of control. Depending on your system needs, choose a mechanical, electro-hydraulic, or proportional valve to provide precise and reliable pressure control.
- Evaluate flow characteristics. Select a valve with suitable flow characteristics to avoid excessive resistance and ensure optimal system performance.
- Check compatibility with your production environment. Ensure that valve materials are resistant to fluid and operating conditions such as temperature and chemical attack.
- Consider the size and installation parameters. Select a valve that physically fits your equipment and is easy to install in the given space.
- Please note additional features. Some Bosch Rexroth valve models have additional features such as damping and check valves that can improve system performance.
- Check compliance with standards. Ensure that the valve meets the required standards and regulations to ensure safety and durability.
- Consult technical experts. If in doubt, contact Bosch Rexroth or your dealer who can help you make the right choice based on the specific requirements of your system.
Installation and Maintenance Tips
Correct installation and regular maintenance of valves guarantee their reliable and durable operation, minimizing the risk of malfunctions and downtime. Below we will provide you with some valve installation tips that you should know before you add equipment into the hydraulic circuits.
- Ensure that the valve is installed according to the manufacturer's instructions, including the correct position and orientation, to ensure optimal operation.
- Use the correct tools and equipment to connect the valve to the system, avoiding over-tightening the fasteners, which could damage the seals.
- Check valves regularly for leaks, damage, or signs of wear to help identify and correct potential problems early.
- Clean valves and replace filters in your system regularly to prevent clogging and ensure smooth hydraulic system performance.
