A-T Controls, Inc. came to be after a 1997 merger between Acutrol Inc and Triac Controls Inc. The company produces manual ball valves, automated ball valve packages, and pneumatic and electric actuators for the control of industrial valves.
What are triac controls?
Triac Controls designs, develops and manufactures valves, actuators and valve control products.
How do you choose valve actuators?
- Move the valve closure member (disc, ball, or plug) to the desired position. ...
- Hold the valve closure member in the desired position. ...
- Seat the valve closure member with sufficient torque to provide the desired shutoff specification. ...
- Provide a failure mode in the event of system failure.
Where is the actuator valve located?
It is the job of the AC actuator to control the opening and closing of the airflow in response to the thermostat, thus controlling air movement and allowing cool air to blow down the ducts and into the house. The AC actuator is located above or below the coil. It can be set to either single speed or variable speed.
What is the purpose of an electric actuator?
An electric actuator is a device that can create movement of a load, or an action requiring a force such as clamping, using an electric motor to create the necessary force.
How does an electric valve actuator work?
How does an electric actuator work? An electric motor will create rotary motion as the spindle, or rotor, rotates. ... A hollow piston rod is attached to the ball screw nut and this creates the linear motion out of, or into the linear actuator as the motor rotates clockwise or anti-clockwise.
How do actuators work?
An actuator is a motor that converts energy into torque which then moves or controls a mechanism or a system into which it has been incorporated. It can introduce motion as well as prevent it. An actuator typically runs on electric or pressure (such as hydraulic or pneumatic).
How does a TRIAC speed control circuit work?
This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the setting of P1. The setting of P1 determines the phase of the trigger pulse that fires the triac.
Which is an example of TRIAC?
Which is an example of TRIAC? Explanation: BT136 is an example of TRIAC. OptoNCDT ILR 1030 and OptoNCDT1420 are laser sensor used for computing distance and objects placed at very high distances.
What is the example of electrical actuator?
Electric Actuators Well-known examples include electric cars, manufacturing machinery, and robotics equipment. Similar to pneumatic actuators, they also create precise motion as the flow of electrical power is constant.Nov 2, 2020
What is actuators and types of actuators?
Actuators receive a source of energy and use it to move something. ... – Electric actuators use some form of electric energy to operate. – Hydraulic actuators use a variety of liquids as a source of energy. – Pneumatic actuators are operated by compressed air.Feb 10, 2020
