Lined diaphragm valves are ideally for shut-off , flow control and throttling of corrosive process media .
- The Diaphragm valve open-close accessory is made of steel petal and soft material . the diaphragm is easy to cut off medium in pipeline . the packing stuff are omitted so the inner leakage and outer leakage are avoided simultaneously .
- Diaphragm: PFA or FEP
- Diaphragm as executing element could be easily cracked in high frequency open-close , so it needs to be exchanged regularly
