motorized butterfly valve
With its energy efficiency, durability, and low maintenance requirements, it offers a cost-effective and reliable option for controlling the flow of fluids and gases, improving overall system efficiency and minimizing downtime.
Advantages and features
-
Excellent flow regulation performance: The rotation angle of the butterfly plate of the motorized butterfly valve can be precisely controlled, from fully closed to fully open, to achieve linear flow regulation. In industries such as food and beverage production that require extremely high fluid flow accuracy, it can ensure that the amount of raw materials added to each batch of products is accurate and correct, ensuring the stability of product quality.
-
High efficiency and energy saving: The electric actuator has advanced design and low energy consumption during operation. Compared with some traditional valve drive methods, electric butterfly valves can save a lot of energy costs for enterprises in long-term use. Taking large chemical companies as an example, many valves are in long-term operation, and the energy-saving advantages of electric butterfly valves can significantly reduce the overall energy consumption of the company.

| 18244 | DFR-01-1200 | 1200 | 154000 | 92300 |
| Note: When the valve uses switch control, Cv is selected when it opens at 90°; when the valve uses analog control, Cv is selected when it opens at 70°. The recommended control angle is 25°~70°, and the optimal control angle is 60°~65°. | ||||
Applications
-
Building water supply and drainage system: In the water supply and drainage pipes of high-rise buildings, motorized butterfly valve is used to control the on-off and flow of water. In the event of an emergency such as a fire, the electric butterfly valves in the relevant area can be quickly closed through the fire control system to prevent the spread of the fire and ensure the supply of fire water.
-
Industrial automation production line: In industrial automation production lines such as automobile manufacturing and electronic equipment production, electric butterfly valves are used to control the delivery of various process fluids, such as coolants, lubricants, cleaning fluids, etc.
-
Mining and metallurgical industry: In mining, it is used to control the delivery of fluids such as slurry and tailings. In the metallurgical industry, electric butterfly valves are widely used in the cooling systems and gas delivery systems of blast furnaces, converters and other equipment to ensure the safe and stable operation of the production process.
FAQ
Q: What's the power consumption of it during normal operation?
A: Its power consumption during normal operation is relatively low. Thanks to the energy - efficient motor design, it can perform its function effectively while minimizing electricity usage, helping you cut down on operational costs in the long run.
Q: How quickly can it respond to control signals?
A: It has a rapid response time to control signals. Advanced drive technology enables it to start, stop, or adjust the valve position within milliseconds, ensuring prompt and accurate regulation of fluid flow according to your process needs.
Q: Can it operate in an environment with high humidity?
A: Yes, it can operate in high - humidity environments. It is well - protected against moisture ingress, with proper sealing and corrosion - resistant materials used in its construction. This ensures that it functions reliably even in damp conditions without suffering from issues like short - circuits or component degradation.
Q: How does it ensure leak - tight performance?
A: It ensures leak - tight performance through a combination of a precisely machined valve disc and a high - quality sealing gasket. The tight fit between the disc and the seat, along with the resilient properties of the gasket, effectively prevents any leakage, maintaining the integrity of the fluid system.
