Understanding Knife Gate Valves

Unique Design

Knife gate valves boast a distinctive design that sets them apart in the world of industrial valves. Their primary feature, a sharp gate, excels at cutting through thick fluids. This capability makes them ideal for applications dealing with slurry, pulp, and other viscous materials.

The construction of these valves allows for minimal resistance against fluid flow. It ensures that even when materials are dense or contain solids, the valve can operate efficiently. The sharp edge of the gate slices through the media, preventing clogs and ensuring a smooth operation.

Flow Path

The flow path within knife gate valves undergoes a nonlinear enlargement as the valve opens. This unique characteristic impacts fluid dynamics significantly. As the gate lifts, it creates an expanding passage for the fluid to flow through.

This gradual increase in the flow area reduces velocity spikes and turbulence often seen in other types of valves. As a result, knife gate valves offer a smoother control over fluid movement, making them suitable for applications where flow rate modulation is crucial.

Full Operation

For knife gate valves to perform optimally, it's essential they are either fully opened or fully closed. Partially opening these valves can lead to disk and seat wear over time. When the valve is not fully open, the gate exposes only part of its surface to the flowing media.

This exposure can cause uneven pressure distribution and accelerated wear on both the disk and seat surfaces. Fully operating the valve mitigates this issue by ensuring that wear is minimized and that the valve maintains its integrity over longer periods.
