Knife Gate Valves
A series of valves especially designed for industrial bulk handling service applications.
Features:
- Can be used as terminal fitting
- Casted Monoblock Design
- The gate is supported by casted wedges
- Two flush parts for water and air allow cleaning of the seat area
- Threaded body holes for easy centering
- The gland packing can be fastened and changed during operation
- Installation in horizontal position
- Can be dissassembled. Material specific recycling is possible
- Possible actuators: hand wheel, chain wheel, pneumatic or electric actuators
General applications:
- Silo outlets
- Power plants
- Food and beverage
- Chemical plants
- Mining industry
- Pneumatic conveyor technology
