Many different types of valves can be used in various industries. One type is the electric ball valve, which has many advantages over other types. The industry most commonly associated with this type of valve is the oil and gas industry, where it is often used to regulate flow rates for hydrocarbons. It also provides significant cost savings versus traditional methods.

  • Quality Assurance: Choose reputable suppliers known for their high-quality electric valves. Look for valves made from durable materials and ensure they meet industry standards for performance and reliability.

  • Compatibility Check: Ensure the electric valve is compatible with your specific application and system requirements. Consider factors such as voltage, pressure rating, flow capacity, and control options to avoid compatibility issues.

  • Technical Support: Seek suppliers that offer reliable technical support and assistance. Having access to knowledgeable experts can help with installation, troubleshooting, and ongoing maintenance.

  • Certifications and Standards: Verify that the electric valve meets industry certifications and standards for safety and performance. Look for certifications such as CE, UL, or ISO to ensure compliance with regulations.

  • Warranty and After-sales Service: Review the warranty terms and after-sales service provided by the supplier. A comprehensive warranty and responsive support can provide peace of mind and assistance if any issues arise.

  • Price and Value: Consider the overall value of the electric valve, taking into account its quality, features, performance, and long-term reliability. Avoid making decisions solely based on the lowest price.

Electric Valve Actuator - How They Work


Electric valve actuators are devices used to control the opening and closing of valves in various applications. They work by converting electrical energy into mechanical motion to actuate the valve. Here’s a simplified explanation of how electric valve actuators work:

  1. Power Supply: The electric valve actuator is connected to a power source, typically electrical power, such as AC or DC.

  2. Motor Operation: The actuator’s motor receives electrical energy from the power supply, which drives its operation. The motor can be powered by different types of motors, such as synchronous or stepper motors.

  3. Gear Mechanism: The motor’s rotational motion is transferred to a gear mechanism within the actuator. This mechanism converts the rotational motion into linear motion.

  4. Valve Control: The linear motion generated by the gear mechanism is used to open or close the valve. It interacts with the valve stem or spindle, causing the valve to move accordingly.

  5. Position Feedback: Many electric valve actuators are equipped with position feedback sensors, such as potentiometers or encoders. These sensors provide feedback to the actuator, indicating the position of the valve, allowing for precise control and monitoring.

  6. Control Signals: The actuator receives control signals from a control system, such as a switch, programmable logic controller (PLC), or a building automation system. These signals determine the desired valve position, whether fully open, fully closed, or somewhere in between.

By utilizing electrical energy and a combination of mechanical components, electric valve actuators provide efficient and precise control over valve operations in various applications, offering convenience, reliability, and automation capabilities.

The FAQs About Electric Actuator Valves

What is a brass electric ball valve? A brass electric ball valve is an important and functional piece of equipment. It controls the flow of water or other liquids in pipes, tanks, and boilers. A brass electric ball valve can maintain pressure or regulate flow rates. 

 The first thing you need to know about the electric ball valve is that it uses a solenoid to control the flow of fluid through a pipe, for example. This means that there are no moving parts in the valve itself. Instead, electricity passes through two coils of wire inside the solenoid which generate magnetic fields on either side of the coil's core--the interaction between these fields causes metal balls suspended by springs to move up or down with respect to one another, opening or closing off selected ports in order to regulate flow.

The electric ball valve is a type of control valve that alters the flow of fluid in one direction. It also has two ports, an input port and an output port. This design enables it to be used as either a shutoff or regulating device. The ball valve is operated with the use of an actuator which can be electrically or pneumatically powered.

Motorized ball valves are typically made up of a number of raw materials. In order to create a motorized ball valve, these raw materials must be machined and assembled together. The most common raw materials used in the manufacturing of a motorized ball valve include brass, steel, and plastic. While each material has its own unique benefits, choosing the right material for your application is important. 

The plumberstar's MOQ is 100 units by usual.

Electric ball valves come in different sizes and have a variety of functions. Depending on the size and type of electric ball valve, the MOQ (minimum order quantity) may vary.

As the name suggests, an electric ball valve is a valve operated by an electric motor. Unlike other valves which use mechanical linkages to open and close them, electric ball valves are remotely controlled by a solenoid. This makes them ideal for use in difficult-to-reach or hazardous locations. They are also very fast and efficient, making them perfect for use in high-flow applications.

There are typically three electric ball valves; ½ inch, ¾ inch,1 inch, and11/4, 1½ inches. The size you need will depend on the project you are working on. For instance, if you're installing an outdoor faucet with a hose bib, then the size will most likely be around ½-inch or ¾-inch. If your project involves plumbing for a bathroom sink that has two sinks, then it's more than likely that you'll require a 1-inch valve because there's always water running in both pipes at any given time...
Electric valves are a vital part of any electrical system. They control the current flow, allowing it to be turned off or on at will. However, not all ball valves are created equal. So it is important to know what you need before making a purchase decision.

When it comes to automation and electricity, there are many different voltages to choose from. So, what's the difference between 24v dc and 230v ac? And which one should you use for your electric ball valve? Here's a breakdown of the pros and cons of each voltage type:

24V DC is a common voltage for small-scale applications, like residential irrigation systems or small machine tools. It can offer reduced power consumption and cost when compared to AC voltages. However, it can also be more susceptible to electrical noise and requires a more complex circuit design.230V AC is the most common commercial voltage in North America. It offers high power capacity and relatively low susceptibility to noise. But it can be costly
