Electric Ball Valve vs Solenoid Valve – What’s the Difference

Electric Ball Valve vs Solenoid Valve

In the world of fluid control systems, valves are critical components to control the flow of fluid in a system. Solenoid and electric ball valves are used to control the flow of fluids, but they are different in terms of design, application, benefits and drawbacks. This post will provide a comprehensive overview of electric ball and solenoid valves so you can confidently choose the right valve for your fluid control system.

What is Electric Ball Valve?

An electric ball valve is a device used to control the flow of liquids and gases. It utilizes an electrically-controlled ball inside a cavity to open, close, or partially block gas or liquid flow. An actuator such as electricity or pneumatic air pressure valves can be remotely and automatically controlled. Electric ball valves can also provide precise control overflows; they generally feature zero leakage when closed and no minimum pressure requirement to operate them.

What is Solenoid Valve?

A Solenoid Valve is a mechanized valve designed to control the flow of liquid or gas in a system using an electrical current. It consists of an electromagnetically-driven coil, plunger, and gate that opens and closes accordingly. When energized, the coil creates an electromagnetic field which attracts the plunger and opens up the valve’s gate, allowing fluid to pass through.

Difference Between Electric Ball Valve and Solenoid Valve


Electric ball valves consist of a ball with a hole in the middle that moves around and changes its position to either close or open a pathway for fluid. In contrast, solenoid valves use an electromagnetic coil to regulate the opening and closing of a valve’s orifice.


Solenoid valves are ideal for small flow applications, whereas ball valves are better suited for larger flow applications. Solenoid valves are commonly used in applications that require fast shut-off and tight control, such as water treatment, gas and oil, and HVAC systems.

Benefits and Drawbacks:

Solenoid valves are compact in size, have low power consumption, and are easy to install and maintain. However, they can only handle small flow rates and have limited temperature ranges. Electric ball valves, on the other hand, can handle higher flow rates and wider temperature ranges for fluids. However, they are larger, consume more power, and require more maintenance.


Solenoid valves are generally less expensive than electric ball valves, making them a more cost-effective option for small flow rate systems. However, if you are dealing with larger flow rates, the cost of using solenoid valves can add up quickly, which may make electric ball valves a more economical option.


Solenoid valves offer digital control by using a computer to regulate the opening and closing of the valve orifice, providing greater precision and accuracy. Electric ball valves, on the other hand, provide analogue control by using a mechanical device to regulate the position of the valve ball, which may not be as precise as solenoid valves.


In conclusion, the choice between electric balls and solenoid valves depends on various factors such as the application, fluid flow rate and temperature, and budget. Both valves have advantages and disadvantages that must be carefully considered before choosing the right one for your fluid control system. Ultimately, an expert in fluid control systems can help you make the best decision based on the specific needs of your project.
