Product Description
Working Principle In-Depth :
The diaphragm valve is an efficient shut-off valve utilizing a diaphragm as the key component for opening and closing. This innovative mechanism ensures a seamless seal by obstructing the fluid with the diaphragm, effectively isolating the valve body cavity from the cover cavity. Crafted from robust materials such as elastic rubber, corrosion-resistant plastics, and other impermeable composites, the valve body options include plastic, fiber-reinforced materials, ceramics, or metal, providing a simple yet effective structure with superior sealing, outstanding corrosion resistance, and minimal fluid resistance. Depending on the operational requirements, choose from manual, pneumatic, or electric drive modes.
Our Distinctive Advantages
Thanks to its groundbreaking design and sophisticated working principle, Wofly's pneumatic diaphragm valve excels in various fields, showcasing significant advantages as highlighted 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. |
