FAQ
2. Precision CNC Machine Workshop
Working Principle:
The diaphragm valve serves as an efficient cut-off mechanism, employing a diaphragm to seal the flow passage and halt fluid movement, effectively separating the valve body from the valve cover. It's constructed from elastic, corrosion-resistant materials such as rubber and plastic for durability. The valve body employs materials like plastic, glass fiber reinforced plastic, ceramics, or metals, offering a simple yet robust design with excellent sealing and corrosion resistance, coupled with minimal fluid resistance. Available in manual, pneumatic, and electric options for versatile applications.
Our Competitive Advantages
Wofly's pneumatic diaphragm valve stands out due to its unique design and ingenious working principle, offering significant advantages across various domains as detailed below:
| 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. |
