Type A: With Limit
Switch (Standard Type)
Function:
The opening & closing opeation is
controlled
by the external control circuit. Output signal comes
from
the power line at open and closed positions of valve. |
 |
Type B: With Additional Switches
Function:
The opening & closing opeation is
controlled
by the external control circuit having 1 NO (normally
open)
& 1 NC (normally closed) output switches.
Construction: With two intermediate position switches |
 |
Type C: With Potentiometer
Function:
The valve opening position is controlled
by
the external control circuit. The output: 500Ω or
1000Ω potentiometer is relative to the valve position.
Construction: With 500Ω, 94 1000Ω. |
 |
Type D: With Potentiometer and Additional
Switches Function:
The Valve opening position is controlled
by the external
control circuit. The output: 1 NO(normally open)&
1NC(normally closed)
output switch with 500Ω or 1000Ω
potentiometer.
Contruction: With potentiometer
and intermediate
position switches. |
 |
Type E: With Modulating Servo Module
(Modulating Type)
Function:
Modulating Type, input signal:
4~20mADC or
1~5VDC; output signal: 4~20mADC.
Contruction:
With servo control module and 1KΩ potentiometer |
 |
Type F: With R/I Converter
Function:
The output signal 4-20mADC is relative to
the valve position.
Construction: With R/I
converter and 1KΩ potentiometer |
 |
DC Motor With Intermediate Position Switch
Function:
By means of polarity exchange from the
external
control circuit to change the rotation. The output
signal:1 No
(normally open) & 1NC(normally closed) output switch.
Construction:With intermediate-position switches. |
 |
3-Phase, 380 VAC Control Circuit for AC
Motor
Function:
By means of the external phase-reversing
circuit to change
the rotation. The output signal: 1 NO (normally
open) & 1NC(normally closed)
output switch.
Contruction: With intermediate position switches. |
