Type A: With Limit Switch (Standard Type)
F u n c t i o n : 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
F u n c t i o n : The opening and closing operation 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: 500  or
1000 potentiometer is relative to the valve position.
Construction: With 500 , or 1000 .
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 500
or 1000 potentiometer.
Construction: 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.
Construction: With servo control module and 1K
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 1K 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.
Construction: With intermediate position switches.
