Control Valve Flow Characteristics - Quiz

2.

What type of characteristic might be best used for liquid level or flow loops?
- Equal Percentage
- Linear
- Quick opening
Correct Answer

A. Linear

Explanation

Linear characteristics are best used for liquid level or flow loops because they provide a consistent and proportional response to changes in the input signal. This means that as the liquid level or flow rate increases or decreases, the output signal will change in a linear and predictable manner. This is ideal for maintaining accurate and precise control over liquid levels and flow rates, as it allows for easy calibration and adjustment of the control system.

3.

A typical application of an equal percentage characteristic might be:
- Temperature and pressure control
- Liquid level control
- Frequent on/off service
- DeviceNet control
Correct Answer

A. Liquid level control

Explanation

Equal percentage valve (most commonly used in valves):
• Temperature and pressure control loops.
• Used in systems where large changes in pressure drop across
the valve are expected.

The type 86(7)92/86(7)93 features a transfer element which implements 3 different characteristics.
- True
- False
Correct Answer

A. True

Explanation

The statement is true because it states that the type 86(7)92/86(7)93 features a transfer element that implements 3 different characteristics. This implies that the type 86(7)92/86(7)93 has a transfer element and this element has the capability to perform three different functions or exhibit three different properties.

5.

It is not possible to customize a characteristic.
- True
- False
Correct Answer

A. False

Explanation

The statement is incorrect. It is possible to customize a characteristic. Customization allows for the modification or adaptation of a characteristic to fit specific needs or preferences.
