Knife Gate Valves
Our range of knife gate valves can be used with liquids, slurries and powders. The standard valve covers most applications but for high pressure, abrasive or corrosive applications variants are available. Our expertise in the Knife gate Valve industry covers the last 20 years in many sectors. We have significant knowledge with the Orbinox range of Knife gate Valves and offer the range of four that are presented below.

Orbinox Type BC Knife Gate Valve
The BC model knife gate is a square port low-pressure valve for highly solid loaded fluids, mainly used in bulk handling and silo outlet applications. Special care should be taken to maintain the correct distance between the flanges and to ensure that they are parallel to the valve body. Incorrect alignment of the valve can cause deformations, which can lead to difficulties in operation. The valve can be mounted in any position with regard to the pipe. However, it is advisable to place it vertically in horizontal pipeline (A) if the installation allows it. With larger valves (= 400x400), heavy actuators (pneumatic, electric, etc.), or with the valve installed horizontally (B) or at an angle (C) on a horizontal pipeline, the installation will require the construction of suitable supports. (See the following diagram and consult the technical department at Orbinox).

The EB model knife gate is a bi-directional valve designed for general industrial service applications. Before installation, inspect the valve body and components for any damage that may have occurred during shipping or storage. Make sure the internal cavities within the valve body are clean. Inspect the pipeline and mating flanges, making sure the pipe is free of foreign material and that the flanges are clean. The placement of a gasket between the valve and the counterflanges is not required, since the valve is equipped with O-rings in the flange face. Special care should be taken to maintain the correct distance between the flanges and to ensure that they are parallel to the valve body. Incorrect alignment of the valve can cause deformations, which can lead to difficulties in operation. The following table gives the maximum torque values for the valve fixing bolts. Also shown is the maximum depth (T) allowed for the tapped blind boltholes drilled into the valve body.Orbinox Type EX Knife Gate Valve
The EX model knife gate is a uni-directional wafer valve designed for general industrial service applications. Special care should be taken to maintain the correct distance between the flanges and to ensure that they are parallel to the valve body. Incorrect alignment of the valve can cause deformations, which can lead to difficulties in operation. The following table gives the maximum torque values for the valve fixing bolts. Also shown is the maximum depth (T) allowed for the tapped blind boltholes drilled into the valve body. The valve can be mounted in any position with regard to the pipe. However, it is advisable to place it vertically in horizontal pipeline (A) if the installation allows it. With larger diameters (> 300 mm), heavy actuators (pneumatic, electric, etc.), or with the valve installed horizontally (B) or at an angle (C) on a horizontal pipeline, the installation will require the construction of suitable supports.
