API600 API602 Gate Valve motorised valve electric actuated gate valve China factory
What is API602 gate valve ?
the API602 gate valve ,same working prinpical and machanism as normal API600 wedge gate valves.The wedge gate valve can only be fully opened and fully closed and can not be adjusted and throttled.The gate valve was designed to be used either fully open or fully closed, because due to the shape of its obturators which have the shape of a wedge, if it were operated partially open, there would be a great loss of pressure and the sealing surface will be damanged under impact of the fluid.it's also designed and manufactured according to the American standard API600,ASME B16.34, flanged end to ASME B 16.5, and tested according API598, has a specific and restricted function to release or block the flow of different types of fluids in pipelines.
so there are less than 10 factories can make the API602 gate valve up to 72 inch.we Represent one of biggest valve manufacturers in China,Nantong High and middel pressure valve co,ltd(TH),for their large size gate valves,high pressure gate valves.
Main features of API602 gate valve
Main Features
- 1)Large size up to 72"(DN1800),and high working pressure up to 2500lbs
- 3)Universal trim:API trim 1(13Cr),trim 5(Stellite Gr.6 faced both wedge and seat) and trim 8(Stellite Gr.6 faced on seat) are available.and other trim numbers depending the the body materials chosen.
- 4)Flanges:ASME B16.5 and ASME B16.47 for 28"-72"
- 5)Bi-directional sealing
- 6)Small flow resistance and pressure loss,due to the straight flow passage and full open wedge.
- 7)Seat face Stellite Gr.6 alloy hardfaced, ground and lapped to a mirror finish.,Stellite hardfaced CF8M wedge is also available on request.
