Wiring & Installing Procedure of 230 volt AC valve

An AC actuator has a 3-wire connection & one of them is for neutral. The other two are control wires. It would help if you didn’t connect these wires at a time. It may burn the actuator. Limit switches are there in the actuator. These switches consume energy during the opening or closing of the valve. We should observe the color-coding of the wires always.

230 volt AC valve is an automatic control solution. It is highly preferable to use. Expense & ease of wiring is the issues in this case. There are three wires- blue, brown & black in the actuator. Blue one is negative or neutral. Black and Brown’s wires are positive. Black one is for controlling purposes.

Sometimes an electric on-off function may fail. You can run the valve in a manual process. Replacing the faulty actuator is the best solution. It is to open or close the valves manually.

The actuator should be set on top of the valve. It can remove and remount smoothly. Maintenance is also flexible if necessary. Setting up of 24-volt electric valve with an actuator is time-saving.

Valve actuators make watery systems harmless and easier to control. Following issues are necessary to set up an AC valve actuator system:

• We should consider the torque requirements of the system. Fluid viscosity and valve size can affect the torque
• The power source intensity of the actuator installation is accountable
• Valve Mounting Connection will depend on the environment & actuators
• Protection from environmental hazards
• Programmed valve actuators can go into effect if there is any power loss. It may cause by an emergency or system failure.
• Controlling the fluid flow rate is an advantage.

Before installation, we should confirm the valve and actuator are in the same position. An ideal procedure is like below:

• Open the valve in a manual system.
• Install mounting hardware on the valve.
• Once actuator screws, tighten all nuts and bolts.
• Actuator conduit entry should be in a normal position perpendicular to the pipeline.
• Exclude actuator cover.
• Wire actuator with proper wiring circuit.
• Turn on the power of the actuator.
• Operate the valve to close the port.
• Replace cover and secure cover screws.

The motor start capacitor provides enough power in an AC voltage actuator. The energized brake holds the motor in a closed position. Then the actuator can detect the open situation of the valve. It rotates back to the closed position. At that time, power to the actuator motor is cut spontaneously.

The operation of this Valve Actuator is simple. The ball valves need to rotate. This rotation is caused by torque. An accurate torque is a must. The torque comes from the motor. Torque capacity is a vital specification for choosing an actuator. It must be greater than the required torque. It may turn the ball valve in a full close or open state. The Valve Actuator operation depends on the response time. The response time or operation time of an electric actuator is inversely proportional to the torque of the actuator. More torque makes a lower response time.

Applications of 230 volt AC Valve Actuator

AC Actuator is suitable for clean gases and liquids, including cold & hot water. Must be sure the valve is fit for the application. The supplies must be ideal for the medium and the temperature. These AC valve actuators are suitable for petroleum, electric power, water treatment, and shipping. Metallurgy, pharmacy, chemical industries are using these actuator valves also. The usage is also found in energy, textile, food processing, and other fields. They are used in factory uses associated with manufacturing valves, pumps, and motors. They can automate industrial valves and many types of process plants.

Other fields are:

• Oil and gas plants
• Wastewater treatment plants
• Power plants
• Food and beverage plants
• Farming and agricultural plants
• Pulp and paper plants
• Vacuum & high-pressure applications
• Swimming pool water pipe
• Gaseous, liquid, gelatinous or viscous media
