Product Description
Working Principle:
The diaphragm valve, a master of flow control, utilizes a diaphragm to manage the passage of fluids, effectively sealing the valve body cavity from the valve cover. Made from elastic, corrosion-resistant materials like rubber and plastic, its body can be constructed from plastic, reinforced glass fiber, ceramics, or metals. Simple in its construction, the valve boasts exceptional sealing, corrosion resistance, and minimal fluid resistance. Operate manually, pneumatically, or electrically, offering versatility to suit your needs.
Our Advantages
Discover the Wofly Advantage: Thanks to its ingenious design and innovative working principle, Wofly's pneumatic diaphragm valve excels in numerous areas, providing unmatched efficiency and reliability.
| 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. |
