FAQ

Working Principle:
The diaphragm valve is an efficient cut-off valve that utilizes a diaphragm as its primary mechanism to control the flow of fluids. It not only halts the flow but effectively separates the valve body cavity from the valve cover cavity. Typically composed of flexible, corrosion-resistant materials such as rubber and plastic, the diaphragm ensures robust sealing and minimal fluid resistance. The valve body itself is crafted from high-quality materials like plastic, glass fiber reinforced plastic, ceramics, or metal, ensuring durability and excellent corrosion resistance. This simple yet effective design allows for manual, pneumatic, and electric operation modes.
Our Advantages
Wofly's pneumatic diaphragm valve, with its innovative design and efficient working principle, offers exceptional benefits that set it apart in numerous aspects, including the following:
| Efficient sealing performance | Pneumatic diaphragm valve uses soft and corrosion-resistant diaphragm as the valve closing part. This design can provide excellent sealing effect and effectively prevent medium leakage. |
| Strong corrosion resistance | Diaphragm materials choose PFA, PTFE materials with high corrosion resistance which make it suitable for treating strong acid, strong alkali and other corrosive media. |
| Simple maintenance | The structure is relatively simple, and there is no packing device, which reduces the potential leakage points. In addition, it has low maintenance requirements, is easy to disassemble and clean, and is especially suitable for occasions requiring frequent cleaning. |
| Accurate control | By controlling the valve opening through the pneumatic actuator, the accurate adjustment of flow can be realized. The response speed is fast, and it can quickly adapt to the change of process parameters. |
| Wide application range | Can be applied to various industries, including chemical industry, pharmacy, food processing and other fields. It is especially suitable for treating media containing particles or viscosity. |
| Good security | Because of the pneumatic driving mode, the potential safety hazards caused by electrical components are avoided, especially in flammable and explosive environments. |
