Product introduction:
Diaphragm valve is a shut-off valve that uses a diaphragm as an opening and closing element to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body and the inner cavity of the valve cover. Diaphragm is commonly made of elastic, corrosion-resistant, and impermeable materials such as rubber and plastic. Valve bodies are often made of plastic, fiberglass, ceramic, or metal lining materials. Simple structure, good sealing and anti-corrosion performance, and low fluid resistance. Used for media with low pressure, low temperature, strong corrosiveness, and suspended substances. According to the structural form, there are ridge type, cut-off type, gate type, etc. According to the driving mode, there are manual, pneumatic, and electric..

Product features:
1. Excellent sealing performance: The diaphragm valve is made of soft materials such as rubber or plastic, which has good sealing performance and can effectively prevent medium leakage. Due to the fact that the valve stem, valve disc and other parts above the diaphragm are not corroded by the medium, the packing sealing structure is eliminated and there will be no medium leakage.
2. Corrosion resistance: The diaphragm material of the diaphragm valve can resist corrosion from various chemical media and is suitable for handling corrosive fluids such as acids, alkalis, and salts. This makes diaphragm valves widely used in industries such as chemical and pharmaceutical industries.
3. Low maintenance cost: Diaphragm valves have a simple structure and fewer moving parts, resulting in lower maintenance costs and longer maintenance cycles.
4. Precise control: Diaphragm valves can achieve precise flow control, suitable for processes that require fine tuning.
5. Low fluid resistance: Diaphragm valves have a simple structure, low fluid resistance, and higher flow capacity than other types of valves of the same specifications.
6. No leakage: The diaphragm isolates the medium from the upper chamber of the valve stem, so there is no packing medium and it will not leak out.
7. Suitable for multiple media: Diaphragm valves are particularly suitable for hazardous chemicals and radioactive fluids, as their valves do not cause contamination and are widely used in product processing, pharmaceuticals, food, nuclear industry, and other industries that do not allow contamination.
