Product Description
Advantages of gate valves
1. Less fluid resistance
2. Less external force required to open and close
3. Free flow of medium
4.When fully open, the sealing surface by the erosion of the working medium is less than the globe valve.
5.Shape is relatively simple, casting technology is better
Technical data
Nominal pressure:1.0MPa/1.6MPa
Shell test pressure :1.5MPa/2.4MPa
Seal test pressure:1.1MPa/1.8MPa
Suitable medium :water,dringking water ,sewage
Features
1.Simple and compact structure,convenient operation,easy installation and maintenance.
2.Reasonable design ,big flow zone ,smoothbore ,no heap of dirty ,small flow resistance.
3.Elastic sealing ,no leakage and long service life.
4.Inter and outer surface of the valve are painted with epoxy resin and disc is coated by rubber.no contamination can effect upon flow medium.
5.Small operation torque,easy opening and closing.
Standard
1.Design standard:ANSI/AWWA C509-94
2.Face to face：ASME B16.10class125
3.Body flange drilling:DIN2532,DIN2533
4.Test standard :API598
