What Is Electric Actuated 3-Piece Ball Valve?

Electric actuated 3-piece ball valve is a type of valve that uses an electric actuator to control the opening and closing of the valve. The 3-piece design of the valve refers to the construction of the valve body, which is made up of three separate pieces that can be easily disassembled for maintenance or repair. The ball valve itself consists of a spherical ball with a hole in the center that allows for the flow of fluid through the valve. When the electric actuator is activated, it rotates the ball within the valve body, either opening or closing the flow of fluid. Electric actuated 3-piece ball valves are commonly used in industrial applications where precise control of fluid flow is required, such as in chemical processing, oil and gas, and water treatment industries.

Benefits Of Electric 3-Piece Ball Valves:

COVNA electric 3-piece ball valves provide the most flexible fluid control solution. It can be customized as threaded connection, flange connection, clamp connection or welded connection to meet your various piping connection needs. Furthermore, the advantage of the 3-piece ball valve is that it is easy to disassemble, which will facilitate your routine valve maintenance and prolong the service life of the valve.

At the same time, the advantage of electric actuators is that they can receive and feedback signals to help you achieve remote control and regulate flow.

The actuator on my automated valve operates, but the valve won’t turn. Why?

Most likely the valve stem or actuator coupling is broken.

The electric actuator limit switches or the pneumatic actuator position stops are not correctly adjusted.

Probably because there is no air pressure to the solenoid or dirt has jammed it. Also, debris might be trapped inside the valve. Or, the air pressure is not sufficient to operate the actuator. Remember: measure air pressure at the actuator, not at the compressor.

Maybe. First, be sure that the actuator torque output is sufficient to turn the valve reliably. Second, you will have to fabricate a custom mounting bracket and coupling to connect the actuator to the valve.

The valve will stop somewhere between full open and close. When power is reapplied to the original circuit, the actuator will complete the cycle.

To make the change just remove the actuator from the valve and turn it, or the valve stem, 90 degrees and remount the actuator.

Remove the actuator from the valve and check the valve stem. Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking.

Remove the actuator from the valve and check the valve stem. Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking.

Check the electric wiring schematic that came with the actuator for the correct hookup. Sometimes a copy is inside the actuator cover. If it is missing, don’t guess about the connections. Call the manufacturer for a schematic.

The actuator is wired incorrectly (check the schematic accompanying the actuator), or the external control switch is not the correct type for the actuator.

Not unless you bought it with an optional speed control.

Actuators and solenoid valves require different types of electrical control switches. SPDT for actuators, SPST for solenoids. Check the actuator wiring schematic for the correct wiring and switch type.
