Brass Electric Ball Valve DC12V/24V | 1/2" to 2" Water Control

Brass Electric Ball Valve – Precise Automated Water Flow Control

Take full control of your water or fluid systems with this heavy-duty Brass Electric Ball Valve. Engineered for reliability and versatility, this motorized valve operates on DC 12V or DC 24V power and features a three-wire, two-control design — making it easy to integrate into irrigation systems, water treatment setups, home automation projects, aquariums, and industrial fluid management applications.

Available in four convenient thread sizes — 1/2", 3/4", 1", and 2" — this valve fits a wide variety of plumbing configurations. The solid copper (brass) body ensures excellent corrosion resistance, long service life, and durability under sustained operational pressure up to 850 kPa. Female threaded connections provide a secure, leak-resistant seal.

Made in Mainland China.

Frequently Asked Questions

Q: What is the difference between DC 12V and DC 24V operation on this brass electric ball valve?

A: Both voltage options power the same motorized actuator mechanism — the valve opens and closes with the same torque and speed. DC 12V is typically used with smaller power supplies and Arduino/Raspberry Pi setups, while DC 24V is more common in industrial PLCs and larger irrigation controllers. Simply select the voltage that matches your power supply.

Q: How does the three-wire, two-control wiring work?

A: The three-wire configuration includes a common (ground/neutral) wire, an OPEN control wire, and a CLOSE control wire. Applying voltage to the OPEN wire turns the ball valve to the open position; applying voltage to the CLOSE wire rotates it to the closed position. This makes it easy to integrate with relay modules, automation controllers, or manual switches.

Q: Is this brass electric ball valve suitable for drinking water or potable water systems?

A: The valve is constructed from brass (copper alloy), which is widely used in plumbing applications. However, please verify that the specific product meets your local potable water standards and regulations before installing it in a drinking water supply line.

Q: What pipe sizes does this electric ball valve fit?

A: This valve is available in four female-threaded sizes: 1/2", 3/4", 1", and 2". These are standard pipe thread sizes compatible with most residential and commercial plumbing fittings. Select the size that matches your existing pipework for a straightforward installation.
