1.5 butterfly valve
It is mainly composed of valve body, butterfly plate, valve stem and driving mechanism. The butterfly plate is like a smart disc, precisely installed in the center of the valve body, closely connected with the valve stem, and can achieve 90-degree rotation through the driving mechanism to open, close and adjust the flow of the valve, which can effectively control the flow of various fluids and ensure the stable operation of the system.
Advantages and features
-
Precise flow regulation: The butterfly valve can achieve precise control of fluid flow. There is a good linear relationship between the rotation angle of the butterfly plate and the fluid flow. The operator can easily achieve fine adjustment of the flow by controlling the opening of the butterfly plate according to actual needs.
Excellent sealing performance: The use of advanced sealing technology and high-quality sealing materials ensures that the butterfly valve can maintain good sealing performance under various working conditions. -
Sturdy and durable material: The valve body and butterfly plate are usually made of high-strength, corrosion-resistant materials. These materials have excellent compressive strength and wear resistance, and can withstand the high-pressure impact and long-term friction of the fluid in the pipeline.
Technical Parameters
| Order code | Model | DN | Valve opening angle flow cv value | |
| 90° | 70° | |||
| 18223 | DFR-01-50 | 50 | 135 | 90 |
| 18224 | DFR-01-65 | 65 | 220 | 144 |
| 18225 | DFR-01-80 | 80 | 302 | 183 |
| 18226 | DFR-01-100 | 100 | 600 | 364 |
| 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

FAQ
Q: Is it suitable for high-pressure or high-temperature applications?
A: It is typically designed for low to moderate pressure applications, but its suitability for high-pressure or high-temperature environments depends on the material and design specifications. If used in extreme conditions, reinforced seals and high-grade stainless steel or other heat-resistant materials may be necessary.
Q: How does it ensure a reliable sealing performance?
A: It features a precisely engineered disc and seat that create a tight seal to prevent leakage.
Q: Can it be used in sanitary or food-grade applications?
A: Many food, beverage, and pharmaceutical industries rely on it for its easy cleaning, smooth internal surface, and corrosion resistance, ensuring compliance with hygiene standards.
Q: What type of actuator options are available for it?
A: The choice of actuator depends on the application requirements, such as precision control, remote operation, or integration into an existing automated system.
