What Are Motorized Valve and Solenoid Valve and Their Application

Unlike solenoid valves, motorized valves are more reliable, safer, and can be used in place of solenoid valves. This article aims to introduce to you in detail the differences and applications of solenoid and motorized valves.

How the Solenoid Valve Works:

A solenoid valve consists of a solenoid coil, a spool, and a valve body. In the event that the solenoid coil is powered or unpowered, it will drive spool action, make fluid flow through the valve body, or be cut off. There are only two possible states for a solenoid valve: open or closed.

What Are the Advantages of Solenoid Valves?

The solenoid valve has been designed and improved over the years, making it safer and more efficient. The valve can be adapted and installed in a variety of locations, making it versatile and adaptable to a variety of applications.

A great advantage of the valve is its speed of closing and opening, which can be done in less than a second.  Using an automated control system is vital when dealing with toxic gases and fluids. Solenoid valves are a viable option for use in a variety of processes and applications.

Solenoid Valve Advantages Breakdown:

• Fast response time

• Remote operation

• Low power consumption

• Cheap replacement parts

• Fits in a variety of machinery and applications

• Compatible with both DC and AC voltage

• Safety external leakage block

• Low and High-temperature usage

• Can be installed vertically or horizontally

Applications Of Solenoid Valve:

An electric solenoid valve is driven by a solenoid coil, which has a small driving force and is more susceptible to voltage impact, so it is generally appropriate for pipelines less than DN50 and below. The switching time is short, and there is a special high-frequency solenoid valve. Utility models are ideal for pipelines with high operating frequency or short switching times and can be automatically reset during power outages.

Solenoid valves can handle a wide range of media, including acid, lye, water, gas, oil, steam, and more. However, for medium viscosity, the cleaning degree has high requirements when installing a solenoid valve before installing a filter, to ensure that the solenoid valve will operate properly, the leakage rate will be low, and security will be high.

In ventilator machines, car wash systems, fountain systems, and other applications.

How Motorized Valve Works:

A motorized valve is a device powered to rotate the motor, thus opening or closing the valve and withstanding voltage shocks. It is possible to adjust the rotation range of the electric valve. The rotating field can be adjusted by inputting the specified current and voltage signals. It is generally used to control the drive by a current signal (4 mA, 0 mA) or voltage signal (0 mV, 1 mV).

Motorized Valve Advantages

The advantage of motorized valves is that they can be operated frequently, without exerting any effort. They are used primarily for regulation purposes and are controlled or piloted by electric or pneumatic servomotors. In general, manual valves are less common.

Applications Of Motorized Valve:

Motorized valves have large driving forces, and they can control large diameter valves, such as globe valves, gate valves, etc., which makes them suitable for large diameter pipelines or places where the flow of pipelines needs to be regulated.

Water, oil, gas, steam, acids, alkalis, and other media can be applied to motorized valves. Motorized valves can adjust the flow of the pipeline, especially for large-diameter pipelines or those requiring flow regulation. Driving force can control large-diameter valves, and motorized valves can control the flow of the pipeline.

When the working environment is more harsh or remote, we recommend using motorized valves, which can also be programmed by a PLC remote control.
