AME 10 Q8

1 / 3

What is meant by a 4:3 control valve?

C) A control valve designed to control the flow of four different fluids through three independent channels.

B) A control valve that operates with a 4:3 pressure ratio between input and output, used for precise pressure control.

A) A control valve with four ports and three positions, used to regulate fluid flow in hydraulic systems.

D) A control valve that alternates between four different flow rates in three distinct stages.

2 / 3

Explain the term "failset" in a control system and provide TWO examples of its application.

D) A failset is a mechanism that accelerates system operations during a failure. Examples include high-speed processors and fast-acting sensors.

A) A failset is a configuration that enhances system performance during a failure. Examples include increased power output and rapid response modes.

B) A failset is a state where a system continues to operate at a reduced capacity when a component fails. Examples include partial valve operation and limited control input.

C) A failset is a predetermined state that a system moves to when it fails to operate correctly. Examples include valves that default to open or close positions and motor-driven actuators that move to a safe position.

3 / 3

Explain the term "failsafe" in a control system and provide TWO examples of its application.

D) A failsafe is a mechanism that enhances the speed of a system during failure. Examples include turbochargers and fast-acting circuit breakers.

C) A failsafe is a feature that causes a system to enter a safe state in the event of a failure. Examples include spring-loaded valves and emergency shutdown systems.

B) A failsafe ensures a system continues to operate even when a component fails. Examples include redundant servers and dual power supplies.

A) A failsafe is a feature that prevents the system from failing. Examples include backup generators and surge protectors.
