What Makes Knife-Edge Gate Valves Ideal for Abrasive & Viscous Fluids

In industries like pulp and paper, wastewater treatment, food processing, and chemical manufacturing, there is often semi-solid sludge, slurry, and stringy pulp. These liquids won't budge from the industrial systems, leading to leaks, clogged valves, and accelerated wear. Many conventional valves fail under these conditions, but knife gate valves play the role here. For industries that depend on uninterrupted flow, investing in knife gate valves is beneficial. You can source it from a reputable knife-edge gate valve manufacturer to minimise operational disruptions and extend the valve's lifespan.

Let's discover in detail how knife-edge gate valves are ideal for abrasive and viscous fluids.

What is a knife-edge gate valve?

A knife-edge gate valve, also known as an edge gate valve, is a specialized industrial valve with a sharp, beveled gate that slices through fibrous, viscous, or abrasive media or slurry. The blade lowers into the flow path, effectively shutting off the medium. The fluid flows freely without central obstruction in the open position. It is an ideal choice for applications that require minimal pressure drop and shut-off.

Why Choose a Knife-Edge Gate Valve?

A problem-solving design

Traditional gate valves have thicker, blunt gates that trap viscous material, leading to clogging. The knife-edge gate valve gearbox is thin and has a sharp-edged gate that cuts through the dense slurries and fluids. When combined with full-bore design and minimal flow restrictions, it prevents build-ups.

Minimal obstruction

A knife-edge gate valve with its thin, sharp gate slides down and up to open or close the flow. It has an arrow gate that cuts straight out and doesn't significantly slow the fluid when the valve is open. It creates a continuous and seamless passage for fluid to flow without reductions in flow area or changes in direction. Moreover, the knife-like gate is entirely lifted out of the fluid when the valve is open, leaving nothing to impede the media flow.

Minimal maintenance downtime

Knife-edge gate valves have a simple design. The valve is made to resist erosion nd scratches from particles in the fluid. Additionally, with less friction and sticking, the valve opens and closes reliably without jamming. These features eliminate the hassle of fixing, cleaning, or replacing the valve, saving time and money.

Don't let clogging and downtime take up your time and money. The knife-edge gate valves are designed for seamless integration into your control systems. So, invest in knife-edge gate valves from a trusted manufacturer, Viral Industries. They are known for their high-quality knife-edge gate valve gearboxes, designed to meet the specific needs of various industries and applications.
