Today, hydraulic systems are commonly found in the automotive, construction and manufacturing industries. Nowadays, almost all huge manufacturing and process plants contain a number of control loops. An electronic valve control is an important part of these control loops and helps them to control the process variables including flow rate, pressure, temperature etc. Keeping these process variables under control is crucial for the accurate happening of a process. 

Flow control valves control the flow rate of the fluid or gases by closing or opening, partially closing or partially opening the passage. Having effective control over these process variables enables the manufacturer to manufacture a high-quality end product. That’s why they are commonly used in various applications either domestic or industrial.

Here we have written types of flow control valves that are almost used in all hydraulic systems:

Direction Controlling Valves:

A Flow control valve is also used to define the direction of the flow. It is responsible for regulating the fluid in the right direction. An electronic valve control pause and resume the flow as per the need. Prefill valves, test valves and spool valves are the most common types of these valves that are utilized to manage the movement of the fluid in hydraulic systems. 

Nowadays, directional valves are also known for the number of ways they provide for the flow of fluid. These ways are equal to the number of ports a valve have. Generally, these electronically controlled valves are characterized by number systems such as 2/2, 3/4 etc. Now the first number defines the number of ports that the valve has and the second number defines the position that it can achieve. 

Pressure Controlling Valve:

An electronic valve control controls and manages the pressure of the fluid so that the hydraulic system can perform the task efficiently. The main purpose of using this valve is to reduce the risk of leakages and potential harm. This flow adjustment valve monitors the pressure of the fluid and keeps that pressure equal to the set value of the user. 

The responsibility of this valve is to keep the pressure of the fluid equal to the required value. In this way, it allows the system to use the accurate energy that is essential to lift up the weight. If the system will utilize a high amount of pressure and energy for all the weights then it will cost you high utility bills.  

Hydraulic Flow Control Valve:

A hydraulic flow control valve is used in the hydraulic system to monitor and adjust the flow of the fluid. This electronic flow control valve contributes to enhancing the efficiency of the system by providing an accurate flow rate of the fluid. It removes the fluctuations and provides a consistent flow rate for the smooth operations of the hydraulic system. Examples of this flow rate controller are speed control valves, throttle valves and manifold-mounted valves.

Final Words:

Hydraulic valves are the essential components of the hydraulic systems. They are specifically designed to fulfil the need of the hydraulic system and have the ability to bear extreme conditions. The selection of the electronic valve control is important to get the expected performance and enhance the lifespan of the system.
