Dufrene and Company, LLC

Dufrene and Company, LLC was founded in 2004 to represent specialty valve products for heavy industries such as pulp & paper, power, mining, water, wastewater, and chemical facilities. To our good fortune, we partnered with a small family-owned manufacturer of knife gate valves located in Hamilton, Ontario Canada. After several years of promoting and selling the North Port Valve brand, we worked out a deal to become the exclusive Agent for North Port Valves in all markets except for the Canadian market where North Port Valves has its own distribution network in all Canadian provinces.

Dufrene & Company, LLC now has a strong network of exclusive distributors promoting and offering North Port Valves throughout the 48 contiguous states, Mexico, and Central and South America. We have developed a complete line of knife gate valves that are technically sound and readily available to our clients. Due to the size and flexibility of our manufacturing programs, we can offer deliveries not normally attainable by our competitors. We concentrate on working with our distributors and clients to solve problems by determining the correct valve design that is application-specific and not just selling another replacement valve.

North Port Valves (NPV)

Contrary to many of your competitors we are exclusive to manufacturing only knife gate valves and their accessories to include the pneumatic actuators. North Port Valves has been in business for over 20 years and is located in the Golden Horseshoe area in Ontario Canada. It is a family-owned business that focuses on quality and workmanship.

We take great pride that most of the materials in our products are supplied by Canadian Companies. A lot of them are local in the Golden Horseshoe area including all our castings. Every valve component is manufactured in our facility, as well as all assembly and testing.

We offer several different styles of knife gate valves that work in many different applications as well as being able to do custom work due to our in-house manufacturing. We also manufacture our own line of pneumatic cylinders specifically designed to fit our valves. We manufacture O Ports, Check, Sampling, and Transmitter valves as well. We are confident that we can produce a knife gate valve for any application.
