How to Select the Best Directional Control Valve for Your Hydraulic System?

Blog | August 6th, 2021

Many machines today are operating through hydraulic systems. Hydraulic systems, after all, have all the components that can support their respective functions and processes.

A hydraulic system generally works by processing hydraulic fluid to generate enough energy for a specific machine. The hydraulic fluid from the system is typically uncompressible and moves from an electric motor to an actuator. As the fluid moves, it can create enough force or power to allow machine components to carry out their respective functions. 

One part of the hydraulic system that you must consider heavily is the directional control valve. This specific part can regulate the control over the direction of the fluid flow within the system. Considering this part can help your system work optimally and avoid sudden system interruptions.

Here are some factors to consider when picking the best directional control valve for your system.

Surrounding Elements

One of the factors that you should consider when picking the best directional control valve for your system is the system’s surrounding elements. The condition of your surroundings must be heavily considered since some of its elements might not be great for some types of directional control valves. You must take note of the average temperature of your surroundings and see if a specific directional control valve can handle it. You must also check if dust particles, dirt elements, and insects are present.

Controlled Media

Another factor to consider when choosing the best directional control valve for you is the media that it will control. Media like compressed air, water, natural gas, inert gasses, and hydraulic oil feature some properties that can only work with certain types of directional control valves. Knowing these things beforehand can help you choose the most suitable one for your system.

Pressure Requirements

The minimum and maximum pressure requirements of your hydraulic system should also be considered when picking and buying its directional control valve. After all, this specific valve comes in a wide array of configurations such as pilot-operated, solenoid-pilot, and manual.

Flow Factor

Numerous types of directional control valves may feature varying flow factors at the same port size, which is why it would be great if you will be identifying the flow factor of the hydraulic fluid instead of relying heavily on port size. Opting for a directional control valve based on the port size may only lead to oversizing, high installation costs, and other unnecessary expenses.

Core Function

One more factor that you should consider in picking the best directional control valve for your hydraulic system is its intended core function. As previously stated, directional control valves may come in a wide array of configurations and types. A 2-position valve can be effective in pressurising and depressurising a fluid power circuit, while a 3-position valve boasts an additional function towards an unactuated valve.
