Description
The unidirectional wafer‐design knife gate valves of the FK series has a monobloc cast body with interior slides for optimum movement of the through conduit during operation and seal wedges.
The unidirectional wafer‐design knife gate valves of the FK series provide high flow rates with low pressure drop. The lower part of the body has two holes for cleaning. Various seal and packing materials are available.
The unidirectional wafer‐design knife gate valve of the FK series has an arrow on the body indicating the flow direction.
The unidirectional wafer‐design knife gate valve of the FK series is suitable for working with dry products like powder and grain. It is completely sealtight, meaning it is recommended for toxic and hazardous fluids. It is generally used for gravity discharge of dry solids.
NOTE: This valve is usually mounted under a hopper, to prevent the accululation of any kind of solids on the seat. The valve has a special body design and it is assembled with the body arrow in the same direction as the fluid. The design of the FK valve seat is the same as for the A valve, but the pressures vary to those which the FK valves work at.
