JPQ series

Product catalog summary

Overview: The document provides detailed technical specifications and features of the JQP series quarter-turn compact electric actuators, designed for modulating control with high reliability and multiple safety functions.

Key Features:

Reduced Parts: Integration of control, power, and I/O sections into a single board reduces parts and simplifies wiring.
Dynamic Brake: High-accuracy position control through a DC braking circuit, applicable to single-phase motors only.
Zero-Cross Triac Driver: Reduces rush current and noise, ensuring stable operation.
User-Friendly Design: Built-in switches allow easy adjustments and settings.
Automatic Output Signal Adjustment: Output signals are set automatically by adjusting the opening position.
Restart Delay Timer: Protects motor and valve from shock by introducing a delay between motor reversals.
Motor Thermal Protection: Stops power feed to prevent overheating if the motor is locked for about 40 seconds.
Monitor Relay: Provides status outputs with large capacity dry contacts.
Auto Phase Correction: Automatically corrects operating direction in case of improper phase connection for three-phase motors.
Long-Life Potentiometer: Extends maintenance intervals.
Anti-Backlash Mechanism: Ensures high-accuracy control by minimizing potentiometer backlash.

Specifications:

Model Options: JQP-S7, JQP-01, JQP-02, JQP-06.
Power Supply: Options for single-phase (100V, 110V, 200V, 220V) and three-phase (200V, 220V) motors.
Output Torque: Ranges from 70 to 500 N·m depending on the model.
Opening/Closing Time: 18/15 seconds for most models, 29/24 seconds for JQP-06.
Mounting Flange: ISO/DIS 5211 standard.
Input Signals: DC 4-20 mA or DC 1-5 V.
Positional Accuracy: ±2.0% FS, with adjustable zero-span and dead band.
Protection Features: Includes restart delay timer, lock protection timer, and motor thermal protection.
Environmental Conditions: Operates in temperatures from -10 to 50°C, with IPW65 protection structure.

Installation and Operation:

Hand Wheel Rotation: Clockwise rotation opens the valve.
Actuator Installation: Uses 8 tap holes for mounting, with options for different configurations.
Stem Nut Customization: Customers are responsible for machining the stem nut bore and key way.

● 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...

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.
