1. General Introduction

2. Working Principle

3. Design Features

• Electric Actuator: High - quality electric actuators are used, which can be powered by various voltage sources such as AC 220V, AC 380V, or DC 24V. These actuators are designed to provide precise and reliable rotational motion to the ball. They can also be integrated with control systems, receiving signals (e.g., 4 - 20mA analog signals for modulating valves) to adjust the position of the ball and thus control the flow rate.
• Ball and Seat Design: The O - shaped ball is typically made of materials like stainless steel, which offers excellent corrosion resistance and durability. The seat, which provides the sealing function, can be made of soft materials such as PTFE (Polytetrafluoroethylene) for good sealing performance and low friction, or metal seats for applications requiring high - temperature and high - pressure resistance.
• Body Material: The valve body is constructed from materials such as cast iron, carbon steel, or stainless steel, depending on the application requirements. For example, in corrosive environments, stainless - steel bodies are preferred, while cast - iron bodies may be suitable for less demanding applications.

4. Applications

• Industrial Processes: In industries like petrochemical, chemical, and power generation, Electric O - shaped Ball Valves are used for controlling the flow of various fluids, including corrosive chemicals, steam, and oil. They can be used in pipelines for on - off control, as well as in some cases for flow regulation in simple systems.
• Water and Wastewater Treatment: These valves are used to control the flow of water in water supply systems, treatment plants, and wastewater disposal systems. Their ability to provide a tight shut - off is crucial to prevent leaks and ensure proper water distribution.
• HVAC Systems: In heating, ventilation, and air - conditioning systems, Electric O - shaped Ball Valves are used to regulate the flow of water or refrigerant, helping to control temperature and maintain comfort levels.

5. Advantages

• Fast Operation: The 90 - degree quarter - turn operation of the ball allows for quick opening and closing, which is beneficial for applications where rapid response times are required, such as in emergency shut - off systems.
• Good Sealing Performance: With proper seat design, Electric O - shaped Ball Valves can provide a tight seal, minimizing leakage. This is especially important when handling valuable or hazardous fluids.
• Remote Control: The electric actuation enables remote control, which is convenient for large - scale industrial plants or systems where manual operation may be difficult or dangerous. It also allows for easy integration with automated control systems, enhancing overall system efficiency.
