We offer several different styles of knife gate valves that work in many application as well as being able to do custom work due to our in house manufacturing.

We also manufacture our own line of pneumatic cylinder specifically designed to fit our valves.


Pulp & Paper

In applications requiring scavenger valves we provide 3”-30” on the pulpers, hydro purge, dethrashers and composters. NPV HD/MD reject cleaner valves are also being widely used throughout the recycle industry and in pulp mill knotter rejects.

Waste water industry

the waste water treatment industry can and do require valves capable of handling much more difficult, heavy slurry type applications that are more similar to ones found in the pulp & paper Industry. For these waste water treatment applications we are having much success replacing other types and valve lines with our Series 200 DUCO Bi-Directional, cavity free valves.


North Port Valve has a complete range of valves and metallurgy choices that will handle many of the tough abrasive slurry, sludge, and process water used throughout the various mining industries. Our NPV O-Port thru gate design valve is especially applicable and performs well in heavy abrasive and scaling applications typically found in Phosphate process industries


Depending on the type of process being used to manufacture cement there are many knife gate applications that require a dependable shutoff and maintenance free knife gate valve. We have supplied the DUCO series 200 Bi-directional valve with cone deflector in both wet and dry processes, slurry applications as well as in the finished product handling systems
