Structural Features:

1. Resiliently sealed moving parts ensure zero internal leakage;

2. Streamlined flow passages minimize pressure loss;

3. Absence of packing glands eliminates external leakage;

4. Diaphragm isolation between valve body and bonnet protects upper components (bonnet, stem, etc.) from media corrosion;

5. Replaceable diaphragm reduces maintenance costs;

6. Diverse lining materials accommodate various media, offering high strength and excellent corrosion resistance.
