Knife Gate Valves of PromArm manufacturing
Knife gate valve - a type of valve where the locking element is designed as a knife with a sharpened edge.
Knife gate valves are commonly used in such industrial branches as: pulp and paper, textile, food, mining, chemical industry, of housing and communal services (sewerage and waste water filtering). They are used at the pipelines with a high percent of abrasive particles in the working media.
Traditional gate valves have a design with a places where the remains of working media can be accumulated (so-called dead zones). Solids gathered there may affect the operational work of the gate valve. Knife gate valves, due to their design, do not have such drawback: they have a knife that comes out while opening, otherwise the sharp edge cuts through solids in the working media while closing that ensures tightness.
