Product Description
Working Principle:
Diaphragm Valve: This cut-off valve leverages a diaphragm as the pivotal opening and closing mechanism, effectively sealing the flow passage and isolating the valve body cavity from the valve cover cavity. Crafted from premium materials such as rubber, plastic, glass fiber reinforced plastic, ceramics, or metals, these valves promise exemplary elasticity, corrosion resistance, and impermeability. Their simple structure ensures superb sealing and minimal fluid resistance. Available in manual, pneumatic, and electric driving modes, these valves are versatile and efficient.
Our Advantages
Remarkable Advantages of Wofly's Pneumatic Diaphragm Valve: Thanks to its innovative design and effective working principle, our pneumatic diaphragm valve stands out in numerous areas, offering unmatched performance 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. |
