The unidirectional wafer‐design knife gate valves of the F series have a one‐piece cast body with guides to support gate and seat wedges.
The unidirectional wafer‐design knife gate valves of the F series provide high flow rates with low pressure drop. Various seat and packing materials are available.
The unidirectional wafer‐design knife gate valve of the F series has an arrow on the body indicating the flow direction.
The unidirectional wafer‐design knife gate valve of the F series is suitable for working with dry products like powder and grain. It is generally used for gravity discharge of dry solids.
NOTE: This valve is usually mounted under a hopper, to prevent any kind of solids accumulating on the seat. It has a special body design and it is assembled with the body arrow in the same direction as the fluid. The design of the F valve seat is the same as for the A valve, but the pressures vary to those working the F valves.
