Three-wire Two-control Electric Ball Valve

A three-line, dual-control electric ball valve is an electric valve that achieves bidirectional opening and closing of the valve through independent control signals. It boasts features such as high reliability, flexible control capabilities, and safety redundancy design. This type of valve is widely applied in various fields, including industrial automation, fire protection, and chemical engineering.

1.Premium Material: The valve body is forged from high-quality brass for superior durability.

2.Excellent Stability: Equipped with a synchronous motor and two angular travel limit switches to maintain the valve's position after a power outage.

3.Low Noise Operation: Generates less than 40 dB of noise during operation.

4.Easy Disassembly: The ball valve and actuator are connected via a nut installation method, allowing for quick and straightforward disassembly.

5.Clog-Resistant: Capable of withstanding high shut-off pressure differentials, ensuring a tight seal without leakage.

6.Long Service Life: Rated for up to 100,000 open-close cycles.

It is suitable for scenarios with relatively simple valve control requirements, such as applications that only require periodic opening or closing of the valve. For example, in small-scale irrigation systems, the valve may be programmed to open daily at specific times for irrigation. After irrigation is completed, the valve can be closed indirectly through other means (e.g., by using a time relay to cut off power to the water pump, thereby stopping water flow and allowing the valve to close).

1Flexible and Precise Control:
Bidirectional Independent Control: The three-line, dual-control design employs separate signal lines for valve opening and closing. This enables independent control over the valve's opening and closing actions, effectively mitigating the risks of signal conflicts or misoperations that may arise in single-line control systems. Such an independent control logic allows for more agile responses to varying operational conditions, achieving precise regulation of the valve's state.
High Control Accuracy: The independent transmission mode of control signals minimizes the potential for signal interference, thereby enhancing the accuracy of valve movements. This makes it particularly well-suited for technological processes that demand fine-tuned adjustments.

2.High Safety and Reliability:
Redundant Control Design: The dual-signal line control mode offers enhanced safety redundancy. In the event of a failure in one signal line, the other can continue to operate independently, ensuring that the valve can still be opened and closed normally during emergencies and preventing safety incidents caused by control failures.
Strong Fault Isolation Capability: The design of independent signal channels ensures that a fault in one direction does not affect the normal operation in the other direction, significantly reducing the overall system failure rate.

3.Strong Compatibility and Expandability:
Adaptable to Diverse Control Systems: The three-line, dual-control electric ball valve can seamlessly interface with mainstream industrial control systems such as PLC and DCS, supporting multiple control protocols to meet the automation needs of various industrial scenarios.
Easy Integration and Expansion: Its standardized interface design facilitates collaborative work with other automation equipment, enabling rapid integration into existing systems. This provides convenience for future process upgrades or functional expansions.

4.Convenient and Efficient Maintenance:
Quick Fault Localization: The independent signal lines for valve opening and closing make troubleshooting more intuitive. When the valve operates abnormally, the fault point can be quickly located by checking the status of the signal lines, thereby reducing repair time.
Modular Design: The valve structure typically adopts a modular design, allowing key components to be replaced independently. This further reduces maintenance costs and downtime.

5.Strong Environmental Adaptability:
High Protection Rating: Yuanlun electric ball valves usually possess a high protection rating (such as IP67), enabling them to effectively withstand the impacts of harsh environments like dust and moisture, thus ensuring stable operation under complex working conditions.
Excellent Temperature and Pressure Resistance: The valve body and sealing materials have undergone special design, allowing them to adapt to extreme working conditions such as high temperatures and high pressures, and thereby extending the service life of the equipment.
