Quarter-Turn modulating control actuator JQP series ◆ Actuator suitable for modulating control ◆ High reliability using microprocessor control ◆ Equipped with kinds of safety functions.

● Reduced number of parts The control section, power section, and I/O section are concentrated into one electric board, the number of parts can be reduced and external wiring connection are easy. ● Adoption of dynamic brake Adopting the dynamic brake by DC braking circuit enables high-accuracy position control. (This function is applied the single-phase motor only.) ● Zero-cross equipped triac driver Because the zero-cross equipped triac is adopted for motor-driving circuit, rush current and noise generation is reduced and stable operation can be offered. ● User-friendly design Adjustment and...

*1: JQ-06 with single phase motor is 5 minutes duty rated. *3: Operation can be chosen from 3 modes: full open operation, full closed operation, and lock in last position.

Machine the stem nut key way and bore required for the valve stem connection, as shown in the figure below (example of full open key position achieved by turning the output shaft in a CCW direction). Hand Wheel Rotation Rotating the hand wheel clockwise will rotate the output shaft clockwise. Actuator Installation The actuator has a total of 8 tap holes used for mounting tap. You can use just 4 of these tap holes (i.e., every second hole-making two sets of opposing holes in a cross configuration) to mount the actuator.
