DSL 102 W11 Final Flashcard

Front

At what point does a safety valve begin to open to release pressure in a system?

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?

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

Which of the following statements is true?
Flow regulating valves maintain a constant flow rate for most pressure range, while flow control valves do not.
Flow control valves maintain a constant flow rate for most of them pressure range, while flow regulating valves do not.
Flow regulating valves can maintain a constant flow rate in the lowest pressures of their pressure range, while flow control valves cannot.
Both flow regulating valves and flow control valves maintain a constant flow rate for most of their pressure range.

Back

Flow regulating valves maintain a constant flow rate for most pressure range, while flow control valves do not.

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

Front

When working with schematics the components, switch's and relay contacts are symbolized as:

Back

in deactivated position.

Front

A normally open switch contact is:

Back

closed when the switch is activated and opens when the switch is deactivated.
