What are knife gate valves?
Knife gate valves are designed for in line or end of pipeline applications for low pressure and have a number of advantages over other valve types.
- Unlike conventional wedge gate valves, there is no wedging action to cause the blade to jam and the overall length is less which helps in confined spaces.
- Unlike ball valves, there are no cavities or dead areas in which material can settle.
- The shorter overall length is an advantage which helps in confined spaces.
- Unlike butterfly valves there are no restrictions in the bore when the valve is fully open and the blade does not have to push material aside when opening and closing.
