Product description

Unidirectional knife gate valve with wafer design. With round input and square output. Body made up of two screwed?down halves, with slides to provide smooth operation. Provides high flow rates with low pressure drop. Various seal and packing materials available.

Utilization

The knife gate valve is suitable for working in very difficult conditions  with  fluids  which  contain  a  large  amount  of solids.
It is very suitable for paper recycling pulp facilities and, in general, sites which work with hard particles such as metal pieces (staples, clips, etc) and stones.
It is best placed horizontally. The output (square) is larger than the input (round), thus avoiding the accumulation of solids  in the  valve and preventing any  interference when shutting the gate.
