The knife gate valve is designed bi-directionally for general industrial application.It is predominantly used in chemical and mining industries as well as sewage treatment or water plants.
There is no groove on the valve seat, that prevents accumulating media on the sealing surface and thus avoids sealing surface leakage or disc blockage caused by media accumulation.
