The piston-type chemical diaphragm valve is a newly developed product by our company, which is comparable to similar advanced products internationally. The characteristics of this series of products are

1. Without a stuffing box, the throttling element is an elastic diaphragm, which can achieve no internal or external leakage when closed, making it suitable for applications where contamination is not allowed and in hazardous areas.

2. The flow path is smooth, with low flow resistance and high flow capacity, making it suitable for use in suspensions with high concentrations and fibrous media.

3. The aluminum alloy die-casting shell and piston-type design structure make it more exquisite in appearance, smaller in size, lighter in weight, and with greater output force..

4. The valve body made of polyvinylidene fluoride (PVDF) and the diaphragm made of polytetrafluoroethylene (PTFE) enhance its corrosion resistance and prolong its working life, making it suitable for use in acid-base and corrosive media.

5. It conforms to Japanese JIS standards and is fully interchangeable with imported products. Based on these characteristics, this product is widely used in various industrial sectors such as petroleum, chemical, power station, pharmaceutical, healthcare, bioengineering, light industry, and food.

The closing and opening of the diaphragm valve are achieved by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down, closing the valve passage. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises, and the valve passage is opened. The valve has no valve stem, sealing gasket, directional seat, etc. The only moving part in the passage is the diaphragm, so there is no rusting or seizure phenomenon, and it has higher stability. With various structural forms and control forms, it can be applied to various fluid control needs.
