Knife Gate Valves

The Knife Gate Valves from Flowrox is a heavy-duty industrial valve engineered for reliable shutoff and flow control in abrasive or corrosive slurry service. Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.

Standard valve designs struggle in abrasive slurry, powder, and corrosive process media, where seat wear and buildup quickly compromise sealing performance. Pinch and knife gate valve designs address this directly — full-bore, unobstructed flow paths in the open position minimize wear surfaces, while elastomer sleeves and bi-directional sealing tolerate backflow and maintain a tight shutoff even after repeated cycling.

Simple, single-sided closing mechanisms keep these valves easy to maintain in the field, which matters in process plants where valve downtime directly affects production. This makes them a standard choice anywhere flow control or isolation is needed on abrasive or corrosive slurry lines.
