Powder and bulk handling

A full bore with nothing to disturb the flow – that offers a knife gate valve when it is opened position. Just as important, the valve must be extremely tight when it is closed.

Historically Stafsjö have supplied MV and HG valves successfully horizontally installed on powder and bulk handling. The HG valve is the natural choice designed for static media columns – it has a straight through bore. The MV valve is a cost-efficient solution that also offers excellent performance and a tight shut-off, preferably with the seat side upwards towards the tank (if not the differential pressure is too high). The stainless steel RKS valve is possible to customize in size from 100x100 up to 1000x1000 and both square and rectangular sizes are available to order.

In some applications there is a strong need to clean out the valve’s inner space after every stroke, why the HG valve has purge/flushing ports as standard from DN 100 and the MV valve has this as an option on the smaller sizes. If required, the purge ports can be positioned to fit the unique customer application.
