1. Selection of electric control valve:
At present, the commonly used control valves in engineering mainly include electromagnetic control valves and electric control valves. However, there are defects in use. For example, solenoid valves are easily blocked by foreign objects, have high water resistance, and require long-term maintenance; although electric valves have no water resistance, they need to control the circuit, so the corrosion of water vapor will affect the service life.
2. How to overcome the influence of scale on the regulating valve to the greatest extent:
Whether it is a solenoid valve or an electric control valve, scale will not only cause leakage of the control valve, but also affect the normal operation of the control valve in serious cases. Therefore, how to eliminate the influence of scale has become a common concern in the industry.
