Uses and characteristics:
The buttertly valve is uesd as opening and closing. or adjusting medium on the pipe of high temperature, high pressure and fireproof. Its main charateristics as below:
1.Tight structure. small volume, light weight, smart operation and convenient using.
2.The valve adopts triple eccentric resience or mutilayer metal sealed structure to achieve zero leakage of sealng.
3.This valve doesn't have flange, so it is convenient ftor thermal insulation of the pipeline.
4.The valve is characterised by high temperature resistance, high pressure rsistance, corrosion resistance and wear resistance, etc.
