Exposed gate

Knife gate valves with an exposed gate can be found in biogas plants.  The knife gate valves are installed upstream and downstream from the fermenter in biomass substrate lines. The gate is wiped off by a tight fitting and pulls clear out of the housing. Wearing parts such as the housing halves, passage ring, gate, etc. can easily be replaced, which is a significant difference compared to conventional knife gate valves.
