Note:
1.We are directly butterfly valve factory in Tianjin, only 2 hours away from Beijing by car.
2.We have more than 150 body moulds for you to choose!
3.Each valve is taken for two times test pressure before leave factory! Every butterfly valves has 24 months guarantee period.
Soft sealing butterfly valve is suitable for water supplying and draining,gas pipe as adjust flux and cut off medium in foodstuff,pharmacy,chemical industry,petroleum,electric power,light textile,paper making etc with temperature≤120℃,nominal pressure≤1.6Mpa,the main characteristic such as:
1.Novel and reasonable design,special structure,light, Easy instllation and mintenance.It can be mounted wherever needed.
2.Tiny operative moment,quick 90 degrees on-off operation.
3.Miniminzed operating torque,energy saving.
4.Flow curve tending to straight line.Excellent regulation performance.
5.Long servie life.Standing the test of tens of thousands opening/closing operation.
6.Bubbles-tight sealing with no leakage under the pressure test.
7.Wide selection of materials, applicable for various medeium.
