Electric Three Piece Threaded Ball Valve

The electric ball valve has a simple structure composed of only a few parts, leading to lower material consumption. Its small size, lightweight, and compact installation requirements make it ideal for various applications. The valve features small driving torque and pressure regulation, allowing easy and agile operation with a simple 90° rotation for quick opening and closing.

Valve Selection and Application Considerations

Choosing the right size and type of electric ball valve is essential when flow control is required. The valve’s construction is particularly well-suited for large-diameter valves, making them widely used in industries such as petroleum, gas, chemical, and water treatment. They are also integral to the cooling water systems in thermal power plants.

Common Types: Clamp and Flange Electric Ball Valves

There are two commonly used types of electric ball valves: clamp type and flange type. The clamp type is connected between two pipeline flanges with double-headed bolts, while the flange type has a flange at both ends that is bolted to the pipeline. These options offer flexibility depending on installation and application needs.

Product Features：

1.Flow Regulation and Sealing Performance

In addition to its basic functions, the electric ball valve has excellent flow regulation capabilities and sealing characteristics. It is particularly dominant in large and medium-caliber, medium and low-pressure applications. When fully open, the valve plate’s thickness is the only resistance the medium encounters, resulting in minimal pressure drop and improved flow control.

2. Sealing Types: Elastic and Metal

Electric ball valves come in two main sealing types: elastic sealing and metal sealing. Elastic seals, which can be embedded in the valve body or around the butterfly plate, offer effective sealing but are limited by temperature. Metal seals, while harder to achieve a complete seal, provide greater durability and can withstand higher operating temperatures, making them suitable for more demanding conditions.

3. Strength Performance and Durability

The strength of an electric ball valve is crucial for withstanding internal pressure. As a mechanical product under medium pressure, the valve must possess sufficient strength and stiffness to avoid rupture or deformation over prolonged use.

Electric Ball Valves Function and Control Mechanism

Electric ball valves serve as pressure-regulating elements in industrial automation, mainly used for remote opening and closing to control pipeline media. They are powered by either a single-phase AC220V or a DC 24V power supply, offering small size, lightweight, reliable performance, and easy integration. These valves also boast a large flow capacity, making them highly efficient for industrial control
applications.
