Rexroth 3DREP6C-21 25EG24N9K4 M Pressure Reducing Valve High Safety 100% New

Product Description:

Advantages and features of Rexroth pressure reducing valves

‌High-precision adjustment and control capabilities‌

Adopting a pilot pressure reducing structure, the main valve and the pilot valve work together to achieve precise pressure control. The proportional pressure reducing valve supports linearized command value pressure characteristics, and the adjustment accuracy can reach within ±1%.

Integrated proportional solenoid and pressure sensing technology, fast response, support dynamic adjustment of output pressure and flow, and adapt to the precise control needs of complex hydraulic systems.

‌Durability and adaptability‌

The valve body is made of cast iron, with a pressure resistance of 315 bar and an applicable temperature range of -30~90℃. The seals are compatible with hydraulic oil, water and other media, and are suitable for harsh working conditions such as mining and metallurgy.

Low noise design (noise <20 decibels), internal flow channel optimization reduces fluid impact and extends valve service life.

‌Energy saving and intelligent functions‌

The proportional pressure reducing valve (such as R901275714) can continuously adjust the pressure through the current signal, and the energy consumption is reduced by 30% compared with the traditional valve. The integrated electronic components (OBE) improve the control efficiency.

Support remote control interface (such as remote control port connected to solenoid valve), suitable for automated production line and IoT integration scenarios.

‌Safety protection mechanism‌

Built-in overload protection function, automatically releases pressure when system pressure exceeds the set value to avoid equipment damage.

Complies with explosion-proof requirements, and the flameproof design is suitable for hazardous environments such as chemical industry and energy.

Precautions for use

‌Installation specification‌

Preferably install it upright on a horizontal pipeline. Tilting may cause uneven force on the valve core; if the water quality contains impurities, a filter with an accuracy of ≥25μm needs to be installed at the inlet.

A safety pressure relief valve needs to be installed within 4 meters after the valve to prevent water hammer impact from damaging pipeline equipment.

‌Commissioning and operation requirements‌

Before commissioning, flush the pipeline thoroughly, remove foreign matter such as welding slag and iron filings, and prevent clogging of the pilot valve throttle hole.

When adjusting the pressure, the pressure needs to be increased gradually (avoid instantaneous high-pressure shock), and the output pressure must not exceed the rated value marked on the nameplate (such as 315 bar).

‌Maintenance and troubleshooting‌

Check the valve core wear and seal aging every 500 hours. In high temperature or high pollution environment, the lubrication cycle needs to be shortened to 300 hours, and high temperature resistant lubricating oil is preferred.

The proportional pressure reducing valve needs to be regularly calibrated to determine the correspondence between the solenoid signal and the output pressure. When the deviation is greater than ±2%, it should be recalibrated.

‌Safety redundancy design‌

It is recommended to configure a bypass loop in the critical system, so that it can quickly switch to the backup pressure reducing valve to ensure continuity in case of failure.

In the automatic control mode, the synchronization of the sensor (such as the pressure feedback module) and the actuator needs to be regularly checked.

(Note: The advantages and features focus on precise control, safety protection and low energy consumption; the precautions cover the core risk points of installation and commissioning, pressure regulation and maintenance)
