Characteristics and sales channels of Rexroth solenoid valve proportional directional valve-Shanghai Nianci Machinery Equipment Co., Ltd，Rexroth directional valve function and usage: 4WEH16E7X/6EG24N9ETK4 is an electro-hydraulic directional valve from the Rexroth brand. Electro hydraulic directional valve is a combination of electromagnetic directional valve and hydraulic directional valve. It uses electromagnetic directional valve to control the action of hydraulic directional valve, thereby changing the direction of fluid flow.

Rexroth electro-hydraulic directional valves and hydraulic control directional valves are mainly used in hydraulic systems where the flow rate exceeds the normal operating range of electromagnetic directional valves, to control the action of actuators or the direction of oil flow. The 4WEH16E7X/6EG24N9ETK4 valve is specifically used to control the opening, stopping, and direction of fluid flow.

Rexroth RexrothCharacteristics of solenoid valve:

1. External leakage blockage, internal leakage easy to control, safe to use

Internal and external leakage is a factor that endangers safety. Other automatic control valvesUsually, the valve stem is extended, and electric, pneumatic, and hydraulic actuators control the rotation or movement of the valve core. This must address the long-term effect of valve stem dynamic sealingThe problem of external leakage; Only solenoid valves rely on sealing and magnetic isolationIt is accomplished by electromagnetic force on the iron core inside the sleeve, without dynamic sealing, which can easily block leaks. Electric valve torque control is not easy, and it is prone to internal leakage, even causing the valve stem head to break; solenoid valveThe structure is easy to control internal leakage until it reaches zero. Therefore, the use of solenoid valves is particularly safe and suitable for corrosive, toxic, or high and low temperature media.

2. The system is simple, can be connected to a computer, and the price is affordable and moderate

Electromagnetic valves have a simple structure and low price, which is more cost-effective than regulating valvesWaiting for other actuators to be easier to install and maintain. More noteworthy is that the automatic control system is much simpler and the price is much lower. Due to the fact that the solenoid valve is controlled by a switch signalIt is very convenient to connect with industrial control computers. In today's era of widespread computer use and significant price drops, the advantages of solenoid valves are even more apparent.

3. Fast action, low power, light design

The response time of solenoid valves can be as short as a few milliseconds, and even pilot solenoid valves can be controlled within a few tens of milliseconds. Due to its own circuit, it is more sensitive than other automatic control valves. Well designed electromagnetic valve coil power consumptionLow is an energy-saving product; It is also possible to automatically maintain the valve position by triggering the action, without consuming any electricity. The solenoid valve has a small volume, which saves space and is lightweight and aesthetically pleasing.

4. Limited adjustment accuracy and applicable medium

Usually, solenoid valves have only two states, and the valve core can only be in two limitsThe position cannot be continuously adjusted. There are many new ideas trying to break through, but they are still in the trial stage, so there are still certain limitations to adjusting accuracy. Electromagnetic valves require high cleanliness of the medium and cannot use granular media. If there are impurities, they must be filtered out first. In addition, viscous media are not suitable, and the viscosity range of media suitable for specific products is relatively narrow.

5. Diverse models and wide applications

Although solenoid valves have their inherent drawbacks, their advantages are still prominent, so they are designed into various products to meet various needs and have a wide range of applications. The progress of solenoid valve technology also revolves around how to overcome inherent shortcomings and how to leverage inherent advantages.
