Design characteristics:
The shutting system is characterized by the double wedge plate gate valve, which is more extensive than that of the elastic wedge, but the dense plates cover the In- and Outlet surely and fully. So complete sealing can be ensured by a gate valve with double-wedge-flat. Besides, the dense strength can be amplified by the operating resource even further.
For the avoidance from inadmissible overpressure with closed gate that arises from heating of enclosure feed water or condensate in the body interior corresponding release furnishings must absolutely be planned. These are: Relief wells cut back with an overpressure protection or with one-sided flow in the seat bush contained to the carrying out side.

By a good gate shutting system is demanded:
- reliable good tightness in the shutoff
- high resistance to wear of the dense faces
- good glide qualities of the seat faces-material
- simple regrinding of the seats faces
- simple dismantling and mounting
