Pneumatic Knife Gate Valves

The FM200 is by far the most frequently used knife gate valve from FERGO Armaturen GmbH. Due to its favorable price and its various optional expansion stages, the FM200 proves to be a real all-rounder for many different applications. As a single-seated knife gate valve, it is ideal for handling solids-laden liquids, for example in the wastewater sector or in biogas applications. Optionally, the valve can be equipped with a bonnet. The bonnet prevents the medium from escaping into the environment and allows the knife-gate valve to be easily installed underwater or on the ground. The bonnet is also recommended for high pressure levels, aggressive liquids and harmful gases. The ingenious and simple design of the housing and seat guarantee long, trouble-free operation with minimal maintenance. The FB200/FM200 knife-gate valve is used, for example, in the paper and pulp industry, power plant technology, water and waste water technology, the chemical industry, the food industry, the bulk goods industry and in other branches of industry. 

The FB700 is the latest knife-gate valve in our product range. The special feature of the FB700 is the smooth passage without dead space in the gate valve housing in combination with a seal on both sides. This means that no solids can build up in the bottom of the housing and the knife-gate valve is also tightly sealed in both flow directions up to the full nominal pressure. As a knife gate valve that seals on both sides, it is particularly suitable for applications in which the direction of flow and/or pressure can change within the pipe. The ingenious and simple design of the housing and the new U-profile plate seal guarantee long, trouble-free operation with minimal maintenance. The areas of application of the FB700 knife gate valve can be found, for example, in the paper and pulp industry, power plant technology, water & waste water technology, chemical industry, food industry, bulk goods industry as well as in many other branches of industry.
