Quarter-Turn
Quarter-turn Actuator
NTIT Series
A smart actuator used with rotary valves such as ball valves and butterfly valves, or with dampers.
Features & Advantages
Self-Diagnostic
Detects internal control errors and displays the cause on the status display, enabling rapid diagnosis and corrective action.
Position Transmitter
A 4–20mA output function is included as standard, allowing the valve opening position to be monitored from the central control room.
Automatic Phase Correction and Calibration
Identifies phase circuits upon power supply, preventing motor reverse rotation and damage caused by incorrect wiring.
Real-time Status Display
Allows real-time monitoring of product status, including torque, commands, operational state, and error alarms.
Data Logging
Records recent commands and errors, providing valuable information for maintenance purposes.
Section Speed Control
Can be configured to repeat run–stop–run cycles within specific sections, accommodating a variety of process conditions.
Over-torque Detection and Resolution
When excessive torque is detected, the motor alternates between forward and reverse rotation to utilize fluid pressure, helping to resolve the issue.
Precision Torque and Position Measurement
Enables accurate torque and position measurement via a high-precision encoder and pressure sensor, with changes viewable in 1% increments on the status display.
Non-intrusive Design
Settings can be configured via infrared remote control without opening the electronic control unit cover, preventing the ingress of dust, moisture, and other contaminants from the field environment.

Quarter-turn Actuator
NTQ Series
A basic actuator equipped with mechanical torque & limit switches, used alongside the NTIT and NTIR with rotary valves, dampers, and similar applications.
Features & Advantages
Position Transmitter
A 4–20mA output function is included as standard, allowing the valve opening position to be monitored from the central control room.
Self-locking
Features a dual worm gear mechanism that prevents positional displacement against reverse torque from the valve.
Thermal Protection
A specially designed insulation Class F motor that achieves high starting torque and high efficiency to prevent damage caused by overheating.
