DSL 102 W11 Final Flashcard

Front

At what point does a safety valve begin to open to release pressure in a system? Options: When the temperature in the system exceeds a predetermined level., When the pressure in the system falls below the valve's pressure setting., When the pressure in the system exceeds the valve's pressure setting., When the flow rate in the system reaches a specific threshold.

Back

When the pressure in the system exceeds the valve's pressure setting.

Front

What is the primary function of a pressure-relief valve in a hydraulic system?

Back

To prevent the system from exceeding pressure limits by releasing excess fluid.

Front

Which components are combined within a one-way flow control valve? A relief valve and a flow control valve. A flow control valve and a check valve. A check valve and a pressure regulator. A pressure regulator and a flow control valve.

Back

A flow control valve and a check valve.

Front

What is the primary function of a check valve in a hydraulic system?

Back

To allow fluid flow in one direction and prevent backflow.

Front

What happens to the flow rate through a control valve when the valve opening is increased?

Back

The flow rate increases.

Front

What is the primary function of a pressure relief valve in a hydraulic system?

Back

To regulate the maximum pressure of the system by diverting excess fluid.

Front

Which component is essential for adjusting the flow rate in a hydraulic system? Options: Actuator, Pressure relief valve, Flow control valve, Solenoid valve

Back

Flow control valve
