Advantages of gate valve: 1.Small fluid resistance 2.The torque for opening and closing is small, so it is easy to open and close. 3.The medium flowing direction is not restricted, and it doesn't disturb flowing and reduce the pressure of pipeline. 4. Short length structure 5. Good sealing performance 6. Simple shape, good casting process, widely used Part name Meterial Body Gray iron, ductile iron, cast steel, stainless steel Gate Ductile iron+EPDM or NBR, stainless steel Allen bolits Carbonization process Seals NBR,EPDM, stainless steel Bonnect Gray iron,ductile iron,cast steel Stem Stainless steel O-ring seals NBR Thrust bearings Tin bronze Bolt Carbon steel,ally steel Gland Ductile iron,cast steel Dust Cover NBR Hand wheel Malleable iron Products Detailes Process Application
