Front

What is the main difference between a pressure regulator and a flow control valve?

Back

Pressure regulators maintain constant pressure, while flow control valves maintain a constant flow rate.

Front

What is the primary function of a variable displacement pump?

Back

To change the pump flow independently of rotation speed.

Front

What does the symbol for a Flow Control, Adjustable-Non Compensated look like?

Back

Front

How does a solenoid valve operate within a hydraulic system?

Back

By using an electrical coil to magnetically move the valve.

Front

What should be done prior to starting hydraulic equipment?

Back

Front

Define a pressure regulator in hydraulic systems.

Back

A device that maintains a constant output pressure regardless of changes in input pressure or flow.

Front

What is the role of a flow control valve?

Back

To regulate the flow rate of fluid in a hydraulic system.

Front

Explain the function of a hydraulic pump.

To convert mechanical energy into hydraulic energy by moving fluid.

Front

What is the purpose of a hydraulic accumulator?

Back

To store energy in the form of hydraulic fluid under pressure.

Front

Describe the function of a check valve in hydraulic systems.

Back

To allow fluid to flow in one direction only, preventing backflow.
