How to do a good job in the mechanical limit adjustment of electric valve actuator?

Adjustment principle of mechanical limit of electric actuator 1, when the electric actuator leaves the factory, the two mechanical limit screws on the device have been adjusted and tightened, there is no special demand, and the user does not need to loosen. 2. If it is necessary to adjust the limit screw, the valve position restricted by the screw should be determined first. When the valve is turned off on the right hand, the right side is the closing limit screw, and the left side is the opening limit screw (when the box cover opening window is upward, the end face is adjusted to the limit screw).

3. When the limit position of the valve (or the required position) is adjusted, the limiting screw is first screwed inward to contact with the end face of the fan-shaped worm gear, and then the ring is returned (making it a safety protection for the stroke limit or over-torque). Finally, the relaxation nut at the outer end of the limit screw is reliably tightened, and the mechanical limit adjustment of the electric actuator is completed. 4. The opening and closing operation test of the limit principle of the electric actuator:

After checking the on/off settings and mechanical limits, the valve is opened or closed three times (using the on/off button on the control and checking the on/off indicator at the same time).

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

After the electric head is connected to the power supply, how to electrically stop the valve switch in place, and then save it.

The electric valve action distance is larger than that of ordinary valves, the electric valve opening and closing speed can be adjusted, the structure is simple, easy to maintain, and can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Due to the cushioning characteristics of the gas itself, it is not easy to be damaged by jamming during operation, but there must be a gas source, and its control system is more complex than that of an electric valve. This type of valve should generally be installed horizontally in the pipeline.

An electric valve simply means using an electric actuator. Control the valve, so that the valve can be opened and closed. It can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve. Simulated action and pressure test should be carried out before the installation of electric valves.

Advantages: Good effect on liquid media and large pipe diameter gases, not affected by climate. It is not affected by the pressure of air compressor.

Disadvantages: high cost, not good in humid environment.
