In the process of using, the brass electric solenoid valve should be maintained regularly, keep the valve clean, and lubricate the transmission part regularly. Once the valve fails, it must stop using immediately, find out the cause of the failure and clean up the failure. Brass electric solenoid valves are suitable for water or liquid, gas as working medium. They can automatically or remotely control the opening and closing of water, gas, oil, liquid and other working medium pipelines. Water solenoid valves have the characteristics of quick opening and closing and high reliability because they are sealed with rubber.
