What is a Hydraulic Valve? Breakdowns, Selection and Tips for Proper Use

What is a Hydraulic Valve?

A hydraulic valve is a fundamental fluid control element in hydraulic systems, controlling the direction, pressure, and flow rate of oil . All movement on hydraulic cylinders and motors directly depends on the correct operation of hydraulic valves.

A poor quality or improperly selected hydraulic valve can lead to a loss of performance, overheating, and catastrophic failures in the system.

What are the Types of Hydraulic Valves?

Directional Control Valves

It determines the direction of movement of the actuators by changing the path taken by the oil. It is commonly used in presses, hydraulic cylinders, and automation systems.

Pressure Control Valves

Protects the system against overpressure. Safety valves directly extend pump and equipment life.

Flow Control Valves

It controls the movement speed by adjusting the flow rate. It plays a critical role in applications where precise speed adjustment is required.

The Most Common Hydraulic Valve Failures

Valve stuckDirty hydraulic oil, particulate build-up

Pressure lossWorn valve body or internal leakage

Jerky operationIncorrect flow selection or improper installation

OverheatingValve structure operating under continuous pressure

How to Prevent Hydraulic Valve Failures?

Regular oil and filter changesChoosing the right pressure and flow valuesUse of quality and standard-compliant valvesProfessional assembly and circuit design

Hidroman offers solutions with a fail-preventing engineering approach in hydraulic systems.

Things to Consider When Choosing a Hydraulic Valve

Maximum system pressure
Flow rate needed
Need for electric or manual control
Operating environment (temperature, dust, humidity)
System security requirements

An incorrectly selected hydraulic valve seriously increases the system cost in the long run.
