Working principle of globe valve

Working principle of globe valve 

The electric valve is usually connected by an electric actuator and a valve, and is installed as an electric valve. The electric valve uses electric energy as power to turn on the electric actuator to drive the valve to realize the switching and regulating action of the valve. Thereby achieving the switching or regulating purpose of the pipeline medium.

The solenoid valve is a kind of electric valve; the magnetic field generated by the electromagnetic coil is used to pull the valve core, thereby changing the opening and closing of the valve body, the coil is de-energized, and the valve core is returned by the pressure of the spring.

the use of electric valves:

Electric valve: Analog adjustment for pipe media flow in liquid, gas and wind systems, is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.

Electric valve: It can have AI feedback signal, which can be controlled by DO or AO. It is more common in large pipes and dampers.

1.Switch form:

The drive of the electric valve is generally a motor, and the opening or closing action requires a certain amount of time to simulate, and can be adjusted.

2.Nature of work:

The electric valve is generally driven by a motor and is more resistant to voltage surges. The solenoid valve is fast open and fast closed. It is generally used in small flow and small pressure, and the electric switch is required in the place where the switching frequency is large. The opening of the electric valve can be controlled. The state has open, closed, half open and half closed, which can control the flow of the medium in the pipeline and the solenoid valve can not meet this requirement.

3.Applicable process:

globe valve sellerstold Electric valves are generally used for adjustment and also have a switching quantity, such as: fan coil end.

The company uses modern management tools to escort the rapid and healthy development of the company through scientific and rational strategic planning and specific implementation strategies.

The company conducts annual strategic meetings every year, constantly formulates and adjusts the company's strategic strategy, making each major decision more forward-looking, scientific and systematic, ensuring that the company continues to develop in the increasingly fierce market competition.
