Analysis of the current situation of domestic solenoid valve market
At present, the electromagnetic valves used in the domestic automatic control system include pneumatic solenoid valves and hydraulic solenoid valves. However, in China, in addition to medium and low pressure and precision, it is generally possible to achieve the level of solenoid valve manufacturing. If users with high accuracy requirements are required to buy imported solenoid valves.
In the past few years, the main body of China's domestic solenoid valve enterprises has developed outward. Although there were many enterprises in the past few years, due to the low cost and unreliable quality, the company could not further develop and the domestic industry market could not be improved. In such a competitive environment, the design and technological content of solenoid valve products are incomparable with solenoid valves. Such solenoid valves, which are bound to be caused by this, are widely favored by users.
Under the situation that the macro-control economy continues to be optimistic, most of the enterprises in the valve industry have experienced rapid growth. However, due to the fierce domestic competition, the price war between enterprises and enterprises, the total sales of the industry have solenoid valves accounted for 70%. That's because manufacturers have core technology, brand and quality advantages.
In 2013, the total import and export volume of the domestic valve industry was nearly 30 billion US dollars, an increase of 30% from the previous month. With the recovery of the world economy, the import and export of valve products has also grown.
Advantages of solenoid valves:
As an actuator solenoid valve for automated meters, demand has risen in recent years. Here is a brief introduction for everyone, the advantages of the solenoid valve:
First, the practicality of the solenoid valve
Practicality is not only the price of the solenoid valve, but also the function and quality of the solenoid valve on a price basis, as well as the cost of installation and maintenance and other accessories. More importantly, the cost of a solenoid valve in the entire automation system or even the entire production line is negligible. Therefore, it is not possible to buy a poor quality solenoid valve that is too cheap or produced by an unknown manufacturer in China, thus causing a safety hazard. All in all, the practicality is not only the quotation of the solenoid valve, but also the most expensive solenoid valve with the most cost-effective safety.
Second, the stability of the solenoid valve
1. The working life of the solenoid valve, this item is not included in the factory test standard, but is a type test standard. It is recommended that in order to ensure the quality, we should choose domestic famous brand products. Of course, many domestic manufacturers do very well.
2. There are three types of work methods: long-term work system, repeated short-term work system and short-term work system. If the valve is open for a long time and only for short-term operation and the batch size is too large, the solenoid valve can be customized to reduce power consumption. Http://
3. If the working frequency requirement is too high, the direct-acting solenoid valve should be preferred, and the power supply should be selected for communication.
