China High temperature Factory Cast steel,Stainless steel Gate Valve China factory Supplier
What is High temperature gate valve ?
the High temperature 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.
but it requires more capacities to produce the API600 large size gate valves.
- 1)moulding system:full set of large moulding for all the body,bonnet,wedge etc.
- 2)equipement:high precision the vertical lathes,drilling,grinding machines for large diameter.
so there are less than 10 factories can make the High temperature 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 High temperature gate valve
- 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.
