What Is The Difference Between Solenoid Valve And Motorized Valve?

As a valve manufacturer, our mission is to help people know the valve and select the right valve. What is the difference between solenoid valve and motorized valve is one of the most frequently asked questions.

In this article, we will introduce from the following 3 points to you. And helping you to understand what is the difference between a solenoid valve and a motorized valve. Hope it is helpful for you.

If you have any demand for motorized valve and solenoid valve, feel free to consult us at sales@covnavalve.com

Motorized valves and solenoid valves are commonly used in industrial control systems to adjust the direction of the media, flow rate, speed and other parameters. Solenoid valve and motorized valve in the performance are different. And now we will show you the difference between them.

1. Differences In Working Principles

Solenoid valve is the use of electromagnetic coil magnetic field to pull the spool, thereby changing the on-off of the valve body, coil power, spool depends on the spring pressure back, control mode for DO digital signal control.

Motorized Valve uses electric actuator control the valve to achieve the valve opening and closing. It can be divided into two parts, the upper part of the electric actuator, the lower part of the valve. The driving device of the motorized valve is a reversible electric motor, which drives the valve core to control the valve through the rotation of the motor for a certain period of time Digital signal control can also be used in a specific pipe environment.

Motorized Valve is divided into two kinds, one is angle stroke motorized valve: From Angle Stroke Electric actuator with angle stroke valve use, to achieve valve 90 degrees internal rotation control pipeline flow on and off; The other is a direct-stroke motorized valve: by the direct-stroke electric actuator with the direct-stroke Valve, the valve plate up and down to control the flow of the pipeline. Usually in a higher degree of automation equipment supporting the use.

The motorized Valve is usually connected by the electric actuator and the valve, after installation and debugging, it becomes the motorized valve. The motorized valve uses electric energy as the power to connect the electric actuator to drive the valve and realize the valve switching and regulating action. To achieve the medium of the pipe switch or adjustment program.

2. Differences In Applications

Solenoid valve can only be used as the switch volume, is DO control, can only be used for small pipe control, common in DN50 and below the pipeline. Solenoid valve has excellent leak-proof performance, open and closes quickly, low power, suitable for some corrosion, toxicity and other chemicals in the pipeline as cut-off use.

Electric Actuator Valve has an AI feedback signal, can also be controlled by DO or AO, often used in large pipelines. Most of them are used to regulate the flow of the pipeline, which are normally installed at the outlet of the air supply and refrigeration pipeline, and can also be used in the liquid pipeline.

3. Differences In The Nature Of Work

Solenoid valve general flow coefficient is very small, and the working pressure is very small. For example, the general 25 mm diameter solenoid valve flow coefficient than 15 mm diameter motorized ball valve much smaller. Solenoid valve is driven through the electromagnetic coil, more easily damaged by voltage shocks. Equivalent to the role of the switch. Solenoid valve switch speed is extremely fast.

Motorized Valve is driven by motor. Motorized Valve opening angle can be adjusted, open or closed to complete the action takes a certain amount of time analog.

Solenoid valve general power can be reset, motorized valve to such a function requires a reset device.

In a summary, solenoid valve and motorized valve both could help to start and stop flow rate.

The features of solenoid valve are fast open and fast close, low cost, compact design, easy to install. Meanwhile, it is suitable for small machines. But it has a limited size range for choice.

The motorized valve could be motorized ball valve, motorized butterfly valve, motorized gate valve and motorized globe valve to achieve start, stop, regulate and separate the flow rate.

Motorized valve has signal feedback and it means it could be controlled remotely and let your project more automated.
Compare with a solenoid valve, a motorized valve could achieve more function but higher cost.

Meanwhile, as an actuator and valve manufacturer, COVNA will provide the quality motorized valve and solenoid valve for your project. Helping you save time and cost.

Solenoid valves and motorized valves are two common types of valves used in industrial and residential applications. Solenoid valves are operated by an electromagnetic coil that opens and closes the valve, while motorized valves are operated by an electric motor that rotates the valve stem to open and close the valve. The main difference between the two is the method of operation and the type of application they are best suited for.
