Electric control valve is simply to use electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into two parts, the upper part is the electric actuator, the lower part is the valve.
There are two kinds of electric valves, one is angular stroke electric valve: the angular stroke electric actuator is used with the angular stroke valve to realize 90 degree internal rotation of the valve to control the pipeline fluid on-off; the other is straight stroke electric valve: the straight stroke electric actuator is used with the straight stroke valve to realize the valve plate up and down action to control the pipeline fluid on-off. It is usually used on the equipment with high degree of automation.
characteristic:
Simple structure and long service life
Suitable for almost all media, the maximum viscosity is 600mm2 / S (CST)
High temperature and chemical resistance
Low cost of explosion-proof, only need to be equipped with small 72 type explosion-proof pilot valve
Electric valve is usually connected by electric actuator and valve, and becomes electric valve after installation and debugging. The electric valve uses the electric energy as the power to connect the electric actuator to drive the valve, so as to realize the opening and closing and regulating action of the valve. So as to achieve the purpose of switching or adjusting the pipeline medium.
Solenoid valve is a kind of electric valve; it uses the magnetic field generated by the solenoid coil to pull the valve core, so as to change the on-off of the valve body. When the coil is powered off, the valve core will return by the pressure of the spring.
