Orbinox Knife Gate Valves for high pressure applications

Here at BM Engineering, we’re big believers in having the right tools for the job. When it comes to applications involving thick media, a knife gate valve can be an invaluable ally to cut through media containing solids. In this article, we explain the design and function of knife gate valves, as well as giving you an overview of our Orbinox knife gate valves.

Knife gate valves are so called because of their ability to cut through media that contains solids. They are a common valve, seen across many industries, for processing very thick media. Knife gate valves tend to be used in pulp and paper, slurry and mining, water treatment, power generation and many other industrial applications. 

Orbinox knife gate valves

We are proud partners of Orbinox UK and hold stock of their knife gate valves in sizes 80mm to 600mm. Both handwheel operated and pneumatic double acting cylinder versions are stocked in cast iron and stainless steel. Other operators – such as chain wheel, handwheel with non-rising stem, lever and electric actuator – are also available direct from Orbinox’s factory in Spain.

Here is just a small selection of some of the knife gate valves that we can supply from the Orbinox range.
