The action force distance of electric valves is larger than that of electric valves. The opening and closing speed of electric valves can be adjusted, with a simple structure and easy maintenance. During the action process, due to the buffering characteristics of the gas itself, it is not easy to be damaged due to jamming, but it must have a gas source, and its control system is also more complex than that of electric valves.

Pneumatic valves have sensitive response, safety, and reliability. Many factories with high control requirements specifically set compressed air stations for pneumatic instrument control components. Electric requires electricity. And a device that can control its flow rate.
1、 What is an electric valve? Simply put, an electric valve uses an electric actuator to control the valve, thereby achieving the opening and closing of the valve. It can be divided into two parts: the upper part is an electric actuator, and the lower part is a valve
There are two types of electric valves, one is the angle stroke electric valve: the electric actuator of the angle stroke is used in conjunction with the valve of the angle stroke to achieve the control of pipeline fluid on-off within 90 degrees of rotation of the valve; Another type is a straight stroke electric valve: it is used by a straight stroke electric actuator in conjunction with a straight stroke valve to achieve up and down movement of the valve plate to control the flow of the pipeline. Usually used in conjunction with highly automated equipment.
2、 Operating principle of electric valves: Electric valves are usually connected by electric actuators and valves, and become electric valves after installation and debugging. The electric valve uses electrical energy as power to connect the electric actuator to drive the valve, achieving the opening and closing and regulating actions of the valve. To achieve the purpose of switching or regulating the pipeline medium.
Electromagnetic valve is a type of electric valve; It uses the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body. When the coil is powered off, the valve core relies on the pressure of the spring to retract.
