DS / Z64H Pipeline Cast steel gate valve water sealed by flange and welding
Chief strucure features and usages
|
1.The chamber of packing of the valve's bonnet is of a water-sealed structure, which, when the water of 0.6-1MPa pressure goes into the mouthpiec, can make the system isolated from air to ensure the system with a good leak proofness |
|
2.Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and fast to open and close, reliable sesling |
|
3.Simple, compact and reaso able structur, easy to overhaul and long duration |
|
4.When to be used as the open&close device on pipelines, it must be in fully-opened or fully-closed state and unallowed to be used for flow adjustment |
|
5.Two ways of connection:by flange and welding, two driving ways:manually and electrically |
|
6.Suitable to act as the open & close device for the pipelines with the working medium of water, steam, oil goods and non-corrosive gas, especially for the vacuum condensation system of the steam tufbine in steam power palnts |
