About Electric valve

The electric valve is usually composed of an electric actuator and a valve. The electric energy is used as the power to drive the valve through the electric actuator to realize the switching action of the valve. So as to achieve the purpose of switching the pipeline medium. Compared with pneumatic valves, electric valves have higher stability, higher control accuracy, better anti-deviation ability, and are more convenient to use because the driving source is a power supply. It is also suitable for valve matching on large-diameter pipelines, and the power supply is used as the power source, and the torque value is sufficient. And can choose the attached handwheel mechanism, as well as explosion-proof, protection level, electric valve is not affected by climate, air pressure. 

However, electric valves are generally complex and prone to failure. Because the motor needs to generate heat during operation, it is easy to cause the motor to overheat, which will increase the wear of the reduction gear. So the service life is not as good as hydraulic and pneumatic actuators. For the wet environment, the opening and closing process of the electric valve is slow, and the entire valve switching action takes 15 seconds. For some requirements, the opening and closing time of the switch is not up to the requirements, and the cost is relatively high. 

In view of the advantages and disadvantages of pneumatic valves and the different conditions of each working condition, Zhejiang Baide Automation will give the best system matching selection according to the actual situation of customers.
