difference between pin type and pinless butterfly valve
1. Price: pin type is cheaper than pinless by 10%.
2. Performance: pinless has better sealing performance and longer service life than pin type.
because the pin will wear and rust and happen to leakage after serve a certain time.
3. After sales: pinless type is easier to replace valve seat or disc than pin type.
Above all, we suggest pin type (ductile iron disc) as an economic choice if butterfly valve will be used for water pipeline, such as HVAC, fire fighting etc.
We suggest to choose pinless type (SS, bronze, PTFE disc) when the media is corrosive, such as chemical or sea water.
