Despite the fact that actuators and ball valves are independent parts, they are most frequently used in conjunction. Therefore, it is easier to assure consistency by purchasing them in a package. You may create an automated ball valve that is remote-controllable by combining an actuator with a ball valve. An interface is used to combine the actuator with the ball valve. The connecting interface consists of a shaft, or stem, that connects the valve ball and a flange that secures the actuator to the valve. An actuator of a specific brand can be installed on a matching valve from the same or recommended brand. On the other hand, as long as they adhere to the same standards, such as the ISO 5211 standard, various ball valves and actuators can be used interchangeably.
An electric actuator is suggested when there is not enough air source present to drive a pneumatically actuated ball valve. Usually, electric-actuated ball valves have slower index times than pneumatic actuators and they can avoid water hammers in high-pressure or velocity situations.
Manufacturers of original equipment (OEM) as well as industrial and commercial applications generally employ electric-actuated ball valves.
What is an Electric Ball Valve?
A quarter-turn valve that automatically controls flow using gearing systems and motors is known as an electric ball valve or electrically actuated ball valve. When the ball’s bore is parallel to the direction of fluid flow, the gearing system and motor system will operate to open the valve. Additionally, it will automatically turn the flow off if the valve handle is turned 90 degrees.
An electric actuated ball valve employs an electric motor to rotate the ball valve by 90 degrees, converting electrical energy into rotational force. They are a silent, clean, and energy-efficient technique for controlling valves. The electric motor can be driven by either alternating current (AC) or direct current (DC). It is contained in a sturdy, small housing along with other actuator parts including gearings, limit controls, wiring, etc. By use of an appropriate connection interface, such as the ISO 5211 standard, the entire assembly is linked to a valve.
If operated in accordance with the manufacturer’s instructions, electric ball valves are recognized for being dependable and having a long service life. Electric ball valve manufacturers constructed these valves to be resistant to corrosion, and withstand high pressure, and high temperature.
Working: Electric Ball Valve.
The electric ball valve is rotated by the power delivered by the electric motor, which is conveyed through a shaft attached to the valve stem. A set of gears is attached to the electric motor shaft in order to produce the necessary torque. An essential criterion to consider while choosing an actuator is the torque capacity. To spin the ball valve by a specific percentage, which is frequently set by the electric ball valve manufacturer, it has to be greater than the necessary torque required, also known as breakaway torque. The ball valve is typically operated with the breakaway torque from the completely closed or fully open static states. An electric actuator’s torque has an inverse correlation with its operating speed (or turnaround time). The connection between speed and torque is determined by the gear system. More torque would be produced but with a low turnaround time with a larger gear ratio.
Direct current with voltages 12, 24, and 48V along with alternating current with a range of voltages 24, 48, 120, 130, and 240V both can be used to operate electric actuators. When closed completely or open, limit switches are provided to halt the current flowing to the motor. Modulating control may be done using electric motors. With this, the valve may be placed precisely at any angle between completely opened and fully closed positions, or within 0° and 90°. This helps to control how quickly fluid flows through the valve. In order to control the electric motor, a positioning circuit board (PCB) is placed in the electric actuator.
Advantages & Disadvantages: Electric Ball Valve.
One of the advantages is that the valve may continue to operate at a high flow rate even when the pressure drops. Because they lack a diaphragm, they have a higher Cv value or flow when matched to a comparable sized solenoid valve.
- They are another easily installed, reasonably priced valve type, similar to solenoid valves. They may be readily incorporated into automation systems using a variety of devices like PCs. An electric ball valve has a lower overall running cost than a solenoid valve since it does not require constant power to keep the position. This characteristic is particularly advantageous to consumers since the ball valve, unlike solenoids, is not vulnerable to burning out.
- An electric actuated ball valve typically takes 2 to 3 extra seconds to operate than a solenoid valve.
- Electric ball valves with medium containing particles in the switching will experience wear and tear, leaks will occur over time, and replacing the ball within will be difficult.
- When compared to a solenoid valve, the initial and operating prices will be higher.
Comparison: Electric & Solenoid Valve.
- Life Cycle: The integrated microswitch of the electric actuator will shut off once the switch is positioned, and it also serves the purpose of maintaining position. Its functionality is reliable, and its life cycle is more than that of a solenoid valve. The coil electrification is necessary for the solenoid valves to open and close. Even when the working position is maintained, the coil must be electrified continuously. When the coil is electrified for an extended period of time, the coil will become hot and will quickly burn out. There are many instances of this sort of error.
- Protection: The shell protects the electric ball valve actuator, and the protection level IP65/IP67 means that dust and moisture may barely damage the inner parts of the actuator, and makes its performance steady. The solenoid valve has a conventional design and minimum protection. Dust, air, and temperature are readily affecting factors.
- Orientation: There is no installation angle required for electric actuated ball valves. The solenoid valve has a straight-stroke operating principle, and in order to achieve sealing, the valve core’s and the electromagnet’s gravitational pull must operate together. The solenoid valve may only be mounted horizontally since any other installation angle would result in solenoid valve leakage.
- Pollution Possibilities: The motion of an electrically actuated ball valve is based on an angular stroke with strong sealing performance on both sides in which leaks are difficult to develop. Straight stroke, diaphragm, or pilot type solenoid valves all operate on the same principle. Impurities in the medium might readily result in leakage since the purity required for the sealing surface is quite high.
- Cost Effectiveness: Electric actuated ball valves operate at 1.6 MPa ambient pressure. The cost of the ball valves, which can produce 13 MPa, isn’t much higher than that of 1.6 MPa. Particularly, high-pressure cost provides several benefits above solenoid valves. High-pressure solenoid valves are typically more costly because pressures greater than 1.0 MPa are regarded as medium and high pressure for solenoid valves.
- Functionality: The electric ball valve actuator also has a manual operation that allows the valve to be controlled manually, which means the opening and shutting without the installation of a bypass standby. By-pass manual valves must be fitted in pipelines since solenoid valves normally lack a feature for manual operation.

Selection Criteria: Electric Ball Valve.
Here are the key criteria to consider while selecting electric ball valves.
- Energy Source: You must pick whether the power supply is alternating current (AC) or direct current (DC). As a result, before selecting an electric ball valve, you must determine what source of electricity you will be working with.
- Size Does Matter: In addition, compare the size of the electric ball valves to the required parameters. That is, the larger the application demands, the larger the measurements of the electric ball valves.
The Materials’ Type: Stainless steel is the primary metal that most electric ball valve manufacturers employ to create actuated ball valves. You may select the stainless steel that best suits the requirements of your electric ball valve installation from a variety of materials and grades.
