Best Features for Proportional Air Valve

The hydraulic circuit is reduced by a proportional air valve. Using a proportional valve will reduce the number of components in the system.

As the input pressure or flow changes, the output pressure or flow changes proportionally. The output is also doubled. This article discusses the benefits and uses of these valves. We will also discuss the features of a proportional air valve

The Proportional Control Valve has the Following Functions:

A variable valve is a valve that can change its output in response to changes in electrical input. These valves are also known as electro-hydraulic valves and have some similarities to servo-hydraulic valves and electric control valves in both. The main difference between the servo valve and a proportional solenoid valve is the Servo valve that can be used in closed-loop systems.

At the same time, proportional electric valve are used in open-loop and closed-loop systems. Proportional air valve‘s can be used as directional control valves or pressure regulating valves. But these valves are mainly used as directional control valves. Operations can be performed using electrical signals. Control signals influence the direction and rate of flow through the valve.

What are the Features of Proportional Solenoid Valves:

These valves have a closed-loop control system. Therefore, the valves are controlled with the help of electrical inputs from sensors. This feature, Therefore, proportional solenoid valves are used in a wide variety of applications. These valves also have some safety features, for example, in the event of a power outage or if the power input is interrupted. The valve will close immediately. Proportional solenoid valves have a long service life and require very little maintenance. Their solenoid operator only has one moving part.

What Material is Used in the Manufacturing of a Proportional Valve:

In a proportional relief valve, The spool is made of hardened steel. And the body is made of high-quality, painted hydraulic casting. Zinc-plated solenoids and housings for electronic devices are made from aluminum. Proportional slider spool on casting. A strong structure is similar to a directional control valve. These valves have a high flow capacity and are also economical. The throttle area is formed by a notch cut into the tube. The size and geometry of the notch determine the flow capacity of a given casing.

How Does a Variable Valve Work:

An electronic proportional flow control valve can be considered a combination of hydraulic valve actuation and advanced electronic control. The hydraulic circuit is reduced by a proportional air valve. Using a proportional valve will reduce the number of components in the system. The accuracy and efficiency of the system are increased by means of variable valves. The proportional directional control valve varies the fluid flow according to the electrical input signal.

This proportional air valve produces an output proportional to the electronically controlled input. There are three outputs: direction, pressure, and flow. The coils in most valves operate on direct current and can be caused by different voltages. This creates a different force, and this force is used to move the reel. These valves are of high efficiency and precision. And the remote operation is another advantage of this valve. These valves can control cylinders or other hydraulic motors.


By reading this post, you know “what is a proportional valve” and what its features are. In this post, we have mentioned in detail how the proportional air valve works and what material is used in its manufacturing. So that you can easily choose the best for your type of application.
