James Duva’s Knife Gate Valves are designed to cut through heavy liquids that have clogged. A knife gate valve is used in a variety of industries, including oil and gas, wastewater treatment, mining, power, and more.
We supply knife gate valves that can be used in rough environments. Available in both unidirectional and bidirectional applications, the design of our knife gate valves ensures a tight shutoff on thick liquids. Our valves are made to the highest standard and can be manufactured to be manual or pneumatically actuated. Our products are made to last the long haul.
How Does a Knife Gate Valve Work?
Knife gate valves work by allowing thick media to pass through with no interference. This works due to the knife chopping the media as it passes through the valve. The knife edge is extremely sharp, and it can cut through paper pulp, grease, oils, slurry, and wastewater. This makes the knife gate valve a versatile tool for many different industries.
The James Duva Advantage
Knife gate valves were originally designed for the paper pulp industry. Thick, stringy pulp would lodge between the wedge and the seat of a normal valve, preventing flow shutoff. Knife gate valves were intentionally designed with a sharp edge to solve this problem by cutting through the pulp. Over time, this function of knife gate valves was extended into other industries.
Since the 1950s there have been many manufacturers of knife gate valves, but many products over the years have had major limitations— notably leakage during valve cycling and a non-cutting gate tip. James Duva produces quality knife gate valves that are designed to survive harsh conditions, cut through thick liquids, and provide a tight shutoff. Our knife gate valve is proficient at cutting, shearing, and closing against solids.
In environments that are abrasive, corrosive, and erosive, our knife gate valves are able to perform at high capacity. If you’re dealing with viscous fluids, a reliable and high performing knife gate valve is invaluable. Our products are the marriage between rugged functionality and precise finesse. Our device is the solution you need to prevent clogs and enable a smoother flow of viscous liquid media.
