High Quality Diaphragm Valve with Air Operated Actuator




Pneumatic Diaphragm Valve is a combination of a diaphragm valve and a pneumatic actuator. It is driven by compressed air to regulate the flow of fluid in pipelines. The valve features corrosion-resistant lining on the body and a resilient diaphragm that ensures complete isolation of the corrosive medium from all moving parts. This design eliminates common issues such as leakage, wear, and clogging. The smooth flow path and low resistance allow for a larger flow capacity. Additionally, it offers reliable performance in fire and explosion protection, making it ideal for use in industrial automation systems where strong acids, alkalis, high-viscosity fluids, or media containing particles are present.
Key Features of Pneumatic Diaphragm Valve:
* Unlike other valves, this diaphragm valve uses a no-filler structure, allowing the rubber diaphragm to fully isolate the corrosive medium and all drive components, reducing the risk of leaks and failures.
* Its smooth internal flow path minimizes resistance, enabling higher flow rates and improved efficiency.
* The body can be lined with various materials like PTFE, offering excellent corrosion resistance and adaptability to different environments.
* The valve integrates multiple components including the body, bonnet, disc, stem, and diaphragm, ensuring structural integrity and reliability.
* The opening and closing of the valve is controlled via a handwheel, with color indicators showing whether the valve is open or closed. Rotating the handwheel clockwise reduces the movement of the disc, causing the diaphragm to lower and restrict the flow. When the valve is open, the color indicator changes accordingly.
