G6K41 Normally open flanged rubber lined diaphragm valve
Diaphragm valve is one special cut-off valve; Compared to other valve, diaphragm valve are equipped with below fetures:
1. No leakage inside due to the elastic seal;
2. Streamlined runner and small pressure loss
3. No need of packing, then no outward leakage
4. Parts above the diaphragm such as bonnet, stem, etc can not be eroded by medium, for the diaphragm cut off the connection between medium and bonnet.
5. Replaceable diaphragm and low maintenance cost
6. Various lining materials to choose for different medium, and good anti-corrosive.
