FERGO - Model FL400 -Knife Gate Valves

The FL400 knife gate valve regulates the bi-directional flow of conveying material. By the use of two unique and fully lined seat rings, which serve as flange gaskets as well, this knife gate valve guarantees a high suitability even for extremely abrading mediums. A massive steel centre grants particulary high stability to the seat rings. The seat rings are compressed by the fitting between two flanges, the closing gate with its rounded edge pulls them apart again. This avoids the development of dead spots, where the medium might build up. The body is constructed two-piece and especially easy to maintain. The different available sizes, pressure stages, materials and drives are shown in the column on the right. For special executions please contact our sales department.
