JOHNSON CONTROLS VA9203-GGA-2Z Electric Actuator 27 In.-lb. Proportional 24vac

Johnson Controls VA9203-GGA-2Z electric actuator is designed to convert electrical energy into rotary force by an electric motor to turn the ball valve up to 90 degrees. This electric actuator controls the flow, pressure control and shut off for slurries, corrosive fluids, normal liquid and gases.

Working Mechanism:

• The electric motor produces a torque that is transferred by a shaft connected to the valve stem for rotating the ball valve.
• To acquire the needed torque, a system of gears is attached to the electric motor shaft.
• The torque capacity is a critical specification for choosing an actuator. It must be higher than the needed torque (breakaway torque) to turn the ball valve by a certain percentage usually stated by the ball valve manufacturer.
• The breakaway torque is the minimum torque needed to turn the ball valve, usually in the completely closed or completely opened static positions.

Features:

• Johnson Controls VA9203-GGA-2Z electric actuator is a direct-mount valve actuator that works on AC/DC 24V power.
• This bidirectional actuator provides precise positioning on Johnson Controls VG1000 Series 1/2, 3/4, and 1 inch ball valves in HVAC applications.
• This electric actuator has a mechanical spring?return system that offers rated torque with or without power.
• It has an optional line voltage auxiliary switch that shows an end-stop position or executes switching functions within the specified rotation range.

Standards and Approvals:

• UL rated
• CE approved

Frequently Asked Questions:

Q. What is the difference between a motor and an actuator?

A. An actuator is a device that provides linear motion, such as a piston. A rod is pushed linearly when we apply voltage. A motor provides rotational movement, such as in a toy car, the motor helps to spin a wheel through gears, reducing the speed while increasing the torque.

Q. How many types of linear actuators are there?

A. Pneumatic, mechanical / electromechanical, hydraulic and piezoelectric are four basic types of linear actuators.

Q. What are some examples of electrical actuators?

A. Some common examples of actuators are stepper motors, jackscrews, electric motors, electric muscular stimulators in robots, etc.

Q. What is the major role of actuators?

A. An actuator is equipment that creates a motion by converting energy and signals going into the system. It delivers either rotary or linear motion.
