How to prevent the sealing surface of the stainless steel solenoid valve from being destroyed

In the stainless steel solenoid valve, the necessity of the sealing surface is obvious. Regardless of which valve product, the maintenance of the sealing surface is generally based on material considerations to improve its compressive strength and improve its corrosion resistance. However, the material of the stainless steel solenoid valve itself limits these two aspects, that is, stainless steel itself has corrosion resistance, but its compressive strength is usually not improved too high. Therefore, it is necessary to avoid damage to the sealing surface of the stainless steel solenoid valve from the material level. In fact, all that can be done has already been done.

All stainless steel solenoid valves must be avoided from other levels. The only way to avoid damage to the sealing surface of stainless steel solenoid valves is from the structural level. Generally, the solenoid valve can only be opened and closed by selecting the full-open and full-sealed methods. This type of method will prompt the sealing surface to bear all the material impact. If it is half-closed, the impact of the material on the sealing surface will be significantly reduced. Therefore, in these aspects, the structural design can be appropriately changed to promote the stainless steel solenoid valve to achieve a stable total flow without fully opening, so that the actual effect of maintaining the sealing surface can be achieved.

The more prominent feature of high temperature solenoid valve is that it can carry out all normal applications in high temperature natural environment. Generally speaking, all the machinery and equipment that can carry out normal work in high temperature natural environment must have heat-resistant materials. Therefore, it is obvious that the reason why high-temperature solenoid valves can be used in high-temperature natural environments is that the temperature resistance of their materials is very good.

The high temperature resistance of materials is one of the levels. In addition to the development heat itself must be resisted, the change in heat generation must actually be considered within the scope of the characteristics of the high temperature solenoid valve. For example, due to the swelling of the material generated by the heat generation, the material of the high-temperature solenoid valve must have a low linear expansion coefficient, otherwise the structural change due to thermal expansion and contraction is very fatal for the valve product.
