Knife gate valves

Expansion areas reduce stress and allow the seats to be axially flexible

Solid top works and robust gland box system for 100% reliability

Reinforced seats guarantee shape and position in the bore during operation improving the stability and performance

Integrated expansion areas provide low operating force and minimize the stress on the seats
