Advantages of Electric Ball Valve

Ease of control and automation

Electric motorized ball valves can be easily controlled and automated, making them ideal for applications requiring precise fluid flow regulation.

Durability and reliability

The motor and ball are enclosed within the valve body, protecting them from external elements and ensuring a long service life.

High flow capacity

These valves are suitable for controlling large volumes of fluids, making them ideal for industrial processes.

Versatility

Velectric motorized ball valves are available in various types, such as two-way, three-way, and multi-port valves, to meet different application needs.

Types of Electric Ball Valve

Leak detection electric ball valve

When the system detects water leakage from an electric ball valve, the built-in sensor will immediately send a signal to control the actuator to swiftly close the ball valve, effectively cutting off the water supply and preventing further leakage or water damage. This automatic shutdown feature can be utilized in household, industrial, or gardening pipeline systems to enhance safety and reduce maintenance costs.

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.

Three-wire one-control electric ball valve

Typically, there are three wires involved. One serves as the common wire, while among the other two, one is used to supply power, and the other functions as the control signal line. The power is connected to the electric valve's drive unit via the common wire and the power-supplying wire. The control signal is transmitted through the common wire and the control signal line to drive the valve to move in one direction, generally capable of controlling only one action of the valve, either opening or closing.

Features of Electric Ball Valve

Intelligent linkage control

Yunnl electric ball valves are typically equipped with highly sensitive water leakage sensors. When a leak is detected, the sensor immediately sends a signal to the electric ball valve, triggering its automatic shutdown action.

Sealing performance

High-quality sealing materials and precise manufacturing processes are employed to ensure that the valve remains leakage-free in the closed state. The sealing designs between the valve body and the ball, as well as between the valve seat and the ball, effectively prevent medium leakage and guarantee the stable operation of the system.

Rapid response

The design of the electric actuator enables the valve to complete opening or closing actions within an extremely short time frame. In the event of water leakage, this rapid response can minimize water waste and potential damage. For instance, certain models of electric ball valves can close within a few seconds after receiving a signal.

Adaptability and installation convenience

This type of electric ball valve is typically designed with universal interfaces, allowing it to be compatible with various pipe specifications and facilitating retrofitting or new installations in existing systems.

Power supply and protection design

Some models adopt a dual-power supply design, enabling the use of a backup power source during power outages to ensure that the valve can still operate normally.

Application of Electric Ball Valve

Water damage protection for households and buildings (proactive whole-house water circuit protection): Tailored for the main water supply system in households, this solution can replace conventional mechanical valves. It automatically shuts off the water inlet within 3 seconds upon detecting leaks in pipes, faucets, or appliances (such as washing machines or water purifiers), thus preventing extensive water damage akin to "a flood overwhelming a mountain."

Zonal water circuit isolation: Suitable for multi-story buildings or villas, this system enables the isolation of water circuits in independent areas such as kitchens, bathrooms, and balconies. When a leak occurs in a specific area, only the corresponding valve is closed, ensuring that water supply to other areas remains unaffected.

Emergency control for special scenarios: Redundant protection for fire water systems. Within the fire protection pipe network, this system can be integrated with the municipal backup pipe network. In the event of a leak in the main water supply line, it automatically switches to the backup water source to ensure an adequate reserve of water for firefighting purposes.

Precision control for agricultural irrigation: In drip irrigation systems, when there is a sudden drop in pressure in a certain branch pipe, the valve can locally isolate the faulty area while simultaneously activating a backup branch pipe to ensure that 95% of the irrigation area remains unaffected.

Electric Ball Valve Components

Actuator: An actuator is a device that converts electrical energy into mechanical motion to operate the valve. In an electric ball valve system, the actuator is typically powered by an electric motor.

Electric motor: The electric motor serves as the primary power source for the actuator, converting electrical energy into rotational motion. Electric motors used in ball valve actuators are often low-voltage direct current (dc) motors for precise control and efficient operation.

Control system: The control system is responsible for sending signals to the actuator to initiate valve opening or closing. It consists of electronic components such as sensors, switches, relays, and programmable logic controllers (plcs).

Position indicator: A position indicator provides visual feedback on the current position of the valve, allowing operators to monitor its status. It typically consists of a visual indicator, such as a mechanical pointer or electronic display, located on the actuator or valve body.

Manual override: Manual override is a critical feature that allows operators to control the valve position manually in case of power failure or emergency situations. It typically involves a handwheel or lever mechanism that can bypass the electric actuation system and directly manipulate the valve.

Power supply: A reliable power supply is essential for the operation of an electric ball valve system. It May be provided by mains power from the grid, batteries, or an external power source, depending on the application requirements and site conditions.

Seals and bearings: Seals and bearings play a crucial role in ensuring the proper sealing and smooth operation of the valve. Seals prevent leakage around the ball and stem, while bearings support the rotating shaft and reduce friction during operation.

Enclosure: An enclosure provides protection for the internal components of the electric ball valve system against environmental factors such as dust, moisture, and temperature fluctuations. It typically consists of a durable housing made of materials such as stainless steel or thermoplastic.

Wiring and connections: Wiring and connections are critical for transmitting electrical signals between the control system, actuator, and power supply.

FAQ

Q: How do electric ball valves work?

A: The electric motor generates a torque, which is transmitted by a shaft connected to the valve stem. This rotates the ball valve.

Q: What is the difference between a solenoid valve and an electric ball valve?

A: Typically, solenoid valves require power to open or close and more power to hold the valve in its energized state. Electric ball valves, though, only use power to open or close and don't require power to stay in that position.

Q: Why use a plug valve instead of a ball valve?

A: Sealing: A plug valve provides a tight seal and is less prone to leaking than a ball valve. Both valves may be prone to leaking if the seals wear out or if debris accumulates in the ports.

Q: How does a 3 way T-port ball valve work?

A: The T-port configuration demonstrates another way a 3-way ball valve works—either mixing two inlet flows or distributing flow to two outlets.

Q: How does a 3-way mixing valve work?

A: The design of a thermostatic three-way mixing valve is based on three connections: one for cold water inlet, another for hot water inlet, and a third for the mixed water outlet. Inside, there is a regulating mechanism with a thermostatic element that responds to changes in the temperature of the flowing media.

Q: How does a 3 way control valve work?

A: In constant flow applications, the bi-directional ports of a 3-way control valve allow water to bypass the coil or load through mixing or diverting. An actuator is used to force an upward and downward movement of the valve's plug which works to open and close off the different ports to redirect pressure and flow.
