Product Description:
The advantages and features of Rexroth hydraulic directional short-tube valve and precautions for use are as follows:
1. Advantages and features
High efficiency and energy saving
The special flow channel design reduces internal impedance, reduces pressure loss, and improves energy efficiency by more than 30%. At the same time, it reduces oil temperature, delays hydraulic oil deterioration, and extends system life.
Fast response
The valve core switching time can be controlled in milliseconds to meet the high-frequency action requirements of automation equipment. The response time of the proportional valve with integrated LVDT feedback is less than 15ms.
Stable and reliable
The oil-immersed electromagnetic action design buffers pressure shocks and has high operating stability; the valve core and valve seat have good sealing and low leakage risk, which is suitable for harsh environments such as dust and vibration.
Flexible control
Supports manual, mechanical, electromagnetic, and hydraulic control methods:
Electromagnetic control is suitable for automated production lines;
Hydraulic/pneumatic control is suitable for high-pressure and high-temperature scenarios;
The proportional valve can achieve stepless adjustment of flow and pressure.
Wide range of applications
The working pressure can reach 315bar, and the special material design meets the needs of different hydraulic systems, covering engineering machinery, wind power pitch control, steel rolling mills and other fields.
2. Precautions for use
Operation mode adaptation
Manual operation is limited to simple scenarios, and frequent switching should be avoided;
Electromagnetic control requires a voltage-stabilized power supply to prevent voltage fluctuations from burning the coil;
Hydraulic/pneumatic operation requires a dedicated actuator.
Maintenance requirements
Regularly check the cleanliness of the oil (NAS 1638 level 6 standard is recommended) to prevent the valve core from getting stuck;
Check the coil resistance (standard value 20Ω±5%) to ensure that the electromagnetic components are normal;
Check the seals every 500 hours to prevent leakage.
System design optimization
For high-pressure scenarios, models with hydrostatic unloading technology are preferred to reduce mechanical wear;
The closed-loop control system needs to be equipped with a high-precision sensor to improve the steady-state accuracy of the proportional valve (±0.5%).
Environmental requirements
Waterproof and dustproof design requires the junction box seal to be intact;
In high temperature environments (>80°C), it is recommended to add a heat sink.
Key tips
When replacing spare parts, use the original disassembly tool (such as R901500000);
Before system debugging, confirm that the mid-position function (such as O/Y/H type) matches the equipment requirements.
