Innovative Working Principle:
The diaphragm valve is ingeniously designed as a cut-off valve utilizing a diaphragm to regulate flow. This versatile component not only closes the flow passage and halts fluid movement but also effectively separates the valve body cavity from the valve cover cavity. Crafted from elastic, corrosion-resistant, and impermeable materials like rubber and plastic, the diaphragm ensures robust performance. The valve body, available in plastic, glass fiber reinforced plastic, ceramics, or metal, boasts a simple structure, exemplary sealing, exceptional corrosion resistance, and minimal fluid resistance. Depending on your needs, it can be operated manually, pneumatically, or electrically.
Unmatched Advantages of Our Products
Thanks to its distinctive design and innovative working principle, Wofly's pneumatic diaphragm valve offers unparalleled advantages across various domains, including:
| 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. |
