Usage/Applications of Knife Gate Valve

This knife gate valve is a new generation gate valve characteristic of small construction, low weight, and high material utilization. It is an ideal product for such sectors including sewage disposal, coal slurry, syrup, sludge, air, slag-water mix, water supply, papermaking, mining, etc.

The knife gate valve adopts metal-to-metal hard sealing or metal-to-rubber soft sealing. In the processing of valve switching on/off, the gate plate and sealing face are provided with special design, featuring limited friction and high durability.

The sealing of the knife gate valve represents a breakthrough in traditional sealing form. Upper cap structure changes large area rectangular sealing face of the upper sealing to small area circular sealing, with much enhanced sealing performance. Based on circular sealing, the valve is further provided with latest floating sealing construction in the world. Thus the upper sealing shares the same useful life with pipeline, so the overall useful life of the valve increases.

After envelope is added to the top of hand wheel, all the moving parts of the gate valve will be enclosed. Therefore, the rotation of lead screws between gate plate and stem will not block because of short supply of lubricating oil. In particular, the valve is applicable for long-term service in severely dusty and dry environment.
