Advantages and features of Rexroth pressure relief valve

I. Core technology advantages

‌Precise pressure control‌

Adopting proportional solenoid operation technology, the pressure regulation accuracy can reach ±0.5%, supporting linearized pressure/set value characteristic curve, and excellent transient response performance.

Some models (such as DBD series) integrate pressure limiting function, and the output pressure fluctuation can be controlled at a low level, suitable for 315 bar high pressure conditions.

‌High reliability and durability‌

Through ISO standard oil port design, it has excellent sealing performance and low risk of internal and external leakage, suitable for corrosive media and complex industrial environments.

Gray cast iron valve body and reinforced sealing structure design, strong wear resistance and long service life.

‌Intelligent adaptation capability‌

Support CANopen communication protocol, seamless integration of automation system, convenient remote control and real-time monitoring.

Modular design (such as DREE series) is compatible with a variety of flow specifications, with a maximum flow of 300 L/min, suitable for hydraulic, fire protection and other scenarios.

Precautions for use

I. Installation and commissioning specifications

‌Installation direction requirements‌

It needs to be installed upright on a horizontal pipe, and the water flow direction marked on the valve body must be consistent with the actual medium flow direction; if the water quality contains impurities, a filter needs to be installed at the water inlet.

‌Pressure test protection‌

When the system is pressure tested, if the test pressure exceeds the nominal pressure of the pressure relief valve, the valve cut-off device needs to be closed in advance to avoid damage to the valve body.

When the outlet pipeline length exceeds 20 meters, it is recommended to increase the diameter of the water discharge pipe to prevent back pressure from affecting stability.

II. Key points for operation and maintenance

‌Working condition monitoring‌

Regularly check whether the pressure after the valve is overpressure. It is recommended to add a secondary pressure reducing valve within 4 meters of the outlet and configure an expansion water tank to absorb water hammer impact.

In high-temperature systems, a check valve needs to be installed between the pressure relief valve and the expansion water tank to avoid interference from hot medium backflow.

‌Maintenance cycle‌

Check the aging of the seals every quarter and replace the failed O-rings or rubber gaskets in time.

When out of service for a long time, the pipeline medium needs to be drained and anti-rust grease should be applied to the inner wall of the valve body.

3. Special scene adaptation

‌High-precision control system‌: Models with electronic integration (OBE) (such as DREE20-6X series) are preferred to ensure signal transmission stability.

‌Heavy load environment‌: Avoid installation in dusty and strong electromagnetic interference areas, and configure a protective shell when necessary.
