Product Description

Working Principle: Understand the advanced mechanisms and engineering principles that drive the exceptional performance of our diaphragm valves.:
Diaphragm Valve Explained: Our diaphragm valve, a pivotal cut-off component, utilizes an elastic diaphragm to effectively manage fluid control. This innovative design separates the valve cavity from its cover, leveraging materials like rubber and plastic for superior elasticity, corrosion resistance, and impermeability. Constructed from top-grade plastic, fiberglass, ceramics, or metal, it promises durability, excellent sealing, and minimal fluid resistance, available in manual, pneumatic, and electric variants.

Our Advantages: Discover the numerous benefits that set our products apart, thanks to our cutting-edge design and innovative approach.
Wofly's Pneumatic Diaphragm Valve Advantages: With its uniquely tailored design and advanced working principles, Wofly's pneumatic diaphragm valve offers unmatched advantages, enhancing operational efficiency and reliability across multiple applications.

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.
