Control valve, also known as control valve, is a device that uses power operation to change the process parameters such as medium flow, pressure, temperature and liquid level in the field of industrial automation process control. It is mainly composed of operating actuator and regulating valve body to receive relevant signals and change the opening of the valve, so as to achieve continuous adjustment of pipeline medium process parameters! However, there are many product types of regulating valves, and the control forms are changeable, and they are constantly updated and changed. Users should be carefully familiar with this classification method!
Pneumatic valve ordering requirements should be known that the valve enterprises will ask the customer's order, the conditions required for the customer's products, and then follow the conditions of the valve to select the valve, and if there is no suitable valve, it is likely to produce Poor consequences.
Electric actuator fault scenario 8: The driver sometimes cannot be opened or closed. Test method:
Electric actuator fault scenario 6: The motor temperature is too high Test method: 1. Check the voltage normally with the instrument. 2. Check if the valve body is too tight, if it is too close to consider the replacement valve body.
Electric actuator failure situation: unable to open or fully Test method:
The failure rate of the electric valve product is very low during use. But sometimes there may be such an electric actuator failure, some faults are often not a problem in the device itself.
