The Actuating Motor 743 is a 24 V floating action actuator designed to operate all tekmar brass mixing valves (710 to 724). It receives a 24 V open or close signal, which causes the motor to open or close the valve. It provides 10 N.m (88 in.lbs) of torque over a 90 degree rotation. This product rotates its output shaft whenever 24 V (ac) is applied between either the counter clockwise or clockwise terminals and the Com terminal. It is compatible with any control having a 24 V (ac) floating output.
