Watts Tekmar Actuating Motor 743

Actuating Motor 743

The Actuating Motor 743 is a 24 V floating action actuator tailored to operate all tekmar brass mixing valves within the range of 710 to 724. It responds to a 24 V open or close signal, prompting the motor to adjust the valve accordingly. With a torque output of 10 N.m (88 in.lbs) over a 90-degree rotation, it ensures efficient valve control. This product rotates its output shaft upon the application of 24 V (ac) between either the counter-clockwise or clockwise terminals and the Com terminal. It boasts compatibility with any control featuring a 24 V (ac) floating output.

Key Features:

  • Provides 10 N.m (88 in.lbs) of torque for effective valve adjustment
  • Electrically limited to 90 degrees shaft rotation for precise control
  • Offers a 117-second open or close time at 60 Hz for efficient operation
