*1. One set of TIIS Flameproof cable gland shall be attached for model AVP200. Two sets are for model AVP201.
*2. Standard nish is equal to previous Y138A. Corrosion proof is equal to previous Y138B.
*3. When the input signal (power) is shut o, select direct action to make the output air pressure of this device zero, and reverse action to make the output at the maximum
air pressure (supply air pressure). Positioner action diers from actuator and control valve action, so be careful in selecting the positioner’s action.
*4. No domestic sales in Japan due to Non-SI unit.

Figure 2. Input-output
characterization
Selection of input characterization
The flow characteristic of a control valve is set by selecting the valve plug characteristic, and the input-output
characteristics of the positioner must be specified as linear. However, if the valve plug flow characteristic, which
depends on the control valve’s shape and structure, does not meet requirements, you can correct the overall flow
characteristic of the control valve by specifying “equal percentage” or “quick opening” for the input-output char-
acteristics of the positioner, as shown in Table 5.
Table 5. Control valve flow characteristics correction by the positioner
Characteristic of valve plug Input-output characterization of positioner Overall flow characteristic of control valve
Linear Quick opening Quick opening
Linear EQ% EQ%
EQ% Quick opening Linear
Note: If the valve plug characteristic is “quick opening,” the overall ow characteristic of the control valve cannot be
linear even if “equal percentage” is set for the positioner’s input-output characteristics. (is is because when
the valve plug characteristic is “quick opening,” the control valve works as an ON/OFF valve and it is dicult
to correct its characteristics by changing the setting of the positioner.)
