The features of a knife gate valve for some corrosive environment
On this page
A knife gate valve is a component that utilizes a blade to cut through clogging of heavy liquids. These valves were designed to work in some of the most corrosive, erosive and abrasive environment in the world, such as sewage, power, paper, coal industry. They are mainly used for solid particles, slurry liquid medium in pipeline, which has the following features.
1. They can scrape the adhesion on the sealing surface and remove the sundries automatically.
2. They have short structure length, which can save raw materials, installation space and effectively support pipeline strength.
3. Their scientific upper sealing design of the stuffing box makes the upper sealing safe, effective and durable.
4. The knife gate valves can only be fully on or fully off; they cannot be used as regulating valves.
5. They shall generally be installed horizontally in piping, must be maintained regularly and should not be bumped or squeezed casually in order to avoid sealing problem.
