Proportional Solenoid Valve Technology

Emerging Trends In Proportional Solenoid Valve Technology:

The proportional solenoid valves are electromechanically controlled valves for auto functioning.  Solenoid valves working need no engineers to operate. The function of a solenoid valve the flow of the media is controlled automatically.

Many plants are taking advantage of the solenoid valves and their automation. There is a variety of designs for solenoid valves. It is possible to maintain the pressure inside the reaction chamber.

The solenoid valve working makes it possible to automatically open and close and hence specially designed to control the flow of the liquid. The solenoid valves then you can precisely control the flow of the material. 

Here, we are discussing the function of a solenoid valve:


Structure of the proportional solenoid valves:

These valves are energized and de-energized by the electrical current. It is easy to control the flow of the liquid by automated closing. 

The main parts of solenoid valves are as follows:

A Coil of solenoid valve:

A  coil along with a moving ferromagnetic core at the centre is placed to control the opening and closing of the orifice. The coil in the solenoid valve is used to produce the magnetism for rotation and automation. The magnetized coil rotates around the plunger. It sends signals about when to open or close the valves.

Iron Plunger of solenoid valve:

The iron plunger moves in the coil, the coil keeps the iron plunger in the middle. When the cool becomes magnetized and energized, it pulls the iron plunger in the middle. This opens the whole of the spring, and the spring is used to return the iron plunger to its actual position. 

What does a solenoid?

The proportional solenoid valves do involve the opening and closing of the small orifice. There are two steps in the solenoid valve working.

The Closing of solenoid valves:

In the solenoid valves, when the iron plunger is at the rest position. Then it closes the small orifice and the solenoid valves stop the flow of liquid. 

In this condition, the flow of inward and outward movement is stopped by the valves. 

When the current passes the coil then proportional solenoid valves create a magnetic field. The magnetic field places the force on the iron plunger and the iron plunger moves and the valve opens. You can control the solenoid valves working by the solenoid valves. The industrial utilization of the solenoid valves makes it one of the best options for users.

Solenoid valves are electromechanical devices that are widely used to control the flow of fluids in various industries. They work by using an electromagnetic coil to move a plunger or a spool, which in turn opens or closes the valve. Solenoid valve technology offers several advantages and disadvantages, which we will explore in detail below.


  1. Quick response time: One of the primary advantages of solenoid valve technology is its quick response time. When the solenoid is energized, the valve can open or close almost instantly, which makes it an excellent choice for applications that require rapid changes in fluid flow.
  2. High reliability: Solenoid valves have fewer moving parts compared to other types of valves, which makes them more reliable and less prone to failure. This is particularly important in applications where downtime can be costly, such as in manufacturing or industrial processes.
  3. Precise fluid control: Solenoid valves can provide precise control over fluid flow, which makes them ideal for applications that require accurate dosing or metering of fluids. They can also be combined with sensors and controllers to automate processes and ensure consistent quality.
  4. Low power consumption: Solenoid valves require very little power to operate, which makes them energy-efficient and cost-effective. They can be used with batteries or low-power controllers, which makes them ideal for remote or portable applications.
  5. Wide range of sizes and materials: Solenoid valves are available in a wide range of sizes and materials, which makes them suitable for various applications. They can be made from plastic, brass, stainless steel, or other materials, depending on the fluid being controlled and the environment in which they are used.


  1. Susceptible to dirt and debris buildup: Solenoid valves are prone to dirt and debris buildup, which can cause malfunctions and reduce their lifespan. It is essential to clean and maintain solenoid valves regularly to prevent clogging and ensure their proper operation.
  2. Limited pressure and temperature range: Solenoid valves have a limited pressure and temperature range, which makes them unsuitable for high-pressure or high-temperature applications. They may also require additional cooling or insulation measures to prevent overheating or damage.
  3. Vulnerable to power surges and electrical interference: Solenoid valves are susceptible to power surges and electrical interference, which can damage the coil and cause the valve to malfunction. It is essential to use surge protection and grounding measures to protect solenoid valves from electrical disturbances.
  4. Limited flow capacity: Solenoid valves have a limited flow capacity, which means they may not be suitable for applications that require high flow rates. In some cases, multiple solenoid valves may be needed to achieve the desired flow rate, which can increase the overall cost and complexity of the system.
  5. Limited compatibility with certain fluids: Solenoid valves may not be compatible with certain fluids, such as aggressive chemicals or fluids with high viscosity. It is essential to select the appropriate valve material and design to ensure compatibility with the fluid being controlled.


It is the movement of the iron plunger which makes it possible to open and close without any difficulty. The proportional solenoid valves can be controlled remotely, as it is possible to change the flow of the liquid. When you can mix the proportional qualities of the reactants, then you can gather the precise output of the product. The whole production system relies on the precise concentration of the chemical. You can’t alter the concentration when you have produced a product.
