Three-position control for 90° or 180° rotation of three-way ball or plug valve position control has wide application opportunities in the field.

Presently, this type of control if and only if; is available by using three namur solenoid valves mounting onto 3-position 90° or 180° pneumatic actuator. Moreover, such a solution also brings setting problems as well as the high cost.

DURAVIS three position-control module are integrated into 90° or 180° rotary pneumatic actuators. Three positioning is easily controlled including water-hammer resistance and delay functions.

General Features:
1-) Sensitive positioning; failure rate ±2°
2-) Low- frequency pulse signal
3-) To convert two-positioned actuator into three position.
4-) Delay control can be adjusted (Both for clockwise and counterclockwise)
