In systems with a high concentration of suspended particles, knife gate valves are a type of gate valve that are often utilized for full open or cut off services. When handling slurry, viscous, corrosive, or abrasive media, these valves are very helpful.
The gate works similarly to a knife in that it efficiently cuts through the medium and effectively breaks up any impurities that may be present in the medium in the pipeline. As a result, the classic gate valve’s leaking phenomena in a medium with solid impurities is fully eliminated. In their fully open state, these valves decrease pressure drop. This makes them simple to operate. Knife gate valves are economical and have a comparatively low weight.
Despite being a unique kind of gate valve, the knife gate valve functions similarly to a regular gate valve but with more advanced features which are being manufactured, supplied and exported by Axegic Valves. A knife-like oblique incision is present on the bottom of the valve plate, which may readily cut through the pipe flow medium. As a result, making shutting the valve very simple and efficient, even when the medium is semi-solid. The knife gate valve has manual, pneumatic, and electric drive modes, and its operating concept is relatively straightforward.
A typical Unidirectional Knife Gate is one of the few application-specific industrial valve designs with a single-piece durable and compact cast body construction that provides the best performance and may be used for simple to sophisticated demanding applications for material flow. A cost-effective, simple-to-use shut-off valve that controls the flow of very viscous fluids via the pipe system. Its design minimises contact between moving components by keeping the gate, which is essentially kept between a few layers of gland packing, from coming into contact with the body parts throughout the majority of its motion. With the help of gate wedges that are situated in the body, the gate and seat are finally sealed using a non-sliding motion.
With the Axegic Unidirectional Knife Gate Valve, you can control fluid flow most innovatively. Precision engineering ensures smooth flow regulation in one direction with unidirectional functionality and reliable shutoff capabilities. Say goodbye to backflow issues with Axegic Valve’s innovation today.
The grooveless knife gate valve is another name for the bidirectional knife gate valve. The body of the cast iron valve is constructed integrally. The bidirectional knife gate valve consists of a U-shaped sealing strip, the gate, and the valve body.
Grooves and an elastic U-shaped sealing strip are present on the bottom of the middle chamber, the valve body’s inlet, and the valve body’s outlet. When the valve is closed, the gate descends and makes contact with the sealing strip at its bottom edge. This forces the sealing strip into the groove, sealing the valve body and gate.
When the bidirectional knife gate valve is opened, the gate moves up, the bottom edge of the gate separates from the sealing strip, the sealing strip springs up, and the groove is flat. This can prevent medium sediment from settling in the groove of the middle cavity of the valve body during use of the knife gate valve, which is not easily blocked and has no residue, and the pipeline is easy to clean, effectively improving the sealing effect of the valve.
For lines with square and rectangular forms, Axegic’s Square Knife Gate Valve and rectangular knife gate valves are designed. The major applications for rectangular Port knife gate valves are the discharge of bins and tanks. For the storage of solid items and highly charged fluids, under hoppers.
Design of a square knife gate valve for increased flow capacity and reduced pressure drop. Internal engineering prevents any accumulation of solids that can hinder valve closure. For a tighter shutoff, internal gates include guides and wedges.
