High Performance Double Disk Gate Valve - DIN-EN Wedge Gate Valve – Nortech
High Performance Double Disk Gate Valve - DIN-EN Wedge Gate Valve – Nortech Detail:
What is DIN-EN Wedge Gate Valve ?
as normal wedge gate valves,the opening and closing parts of the DIN-EN Wedge Gate valve are the gate,in shape of a wedge,that’s the reason that they are named as wedge gate valve. 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.The main feature of a DIN-EN wedge gate valve is that its sealing surface between the “gate” and its seat is flat,which results in the very small pressure loss.
DIN-EN wedge gate valve
- 1)Designed and manufactured according to the BS EN 1984,or former Germany standard DIN3352
- 2)Flanges conforms to EN1092-1,and face to face EN558-1 or former Germany standard DIN3202
- 3)Tested and inspcted according EN12266,BS6755 and ISO5208
Main features of DIN-EN Wedge Gate Valve ?
Main Features
- Size up to DN1200,and high working pressure up to PN100.
- Bi-directional sealing
- Seat face Stellite Gr.6 alloy hardfaced, ground and lapped to a mirror finish.
- Flexible wedge with low center stem-wedge contact, in solid CA15 (13Cr) or hardfaced with 13Cr, SS 316, Monel or Stellite Gr.6. Wedge is ground and lapped to a mirror finish and tightly guided to prevent dragging and seat damage.
- Flanges:EN1092-1,PN10-16-25-40-63-100,or other flanges dimensions requested
- A Stellite hardfaced CF8M wedge is also available on request.
- Small flow resistance and pressure loss,due to the straight flow passage and full open wedge.
- Compact form,simple structure,makes it easy for manufacturing and maintenance,and wide range of application.
- long time to shut down and slow movement of the wedge,no water hammer phenomenon for the wedge gate valves.
