What is a gate valve and where is it used? - AVK valves

Gate valves can be divided into two main types: Parallel and wedge-shaped. The parallel gate valves use a flat gate between two parallel seats, and a popular type is the knife gate valve designed with a sharp edge on the bottom of the gate. The wedge-shaped gate valves use two inclined seats and a slightly mismatched inclined gate.

Gate Valve - Gate Valves Manufacturers

2017-3-21  Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

Gate Valve - an overview ScienceDirect Topics

The knife gate valve is different from other gate valves in that the gate is not totally enclosed within the body, see Figure 3.8. The gate lifts out of the body as the valve opens. The packing box is not circular but rectangular. The packing seals the gate itself against the body. Glands cannot be of screwed or union types and are always bolted.

Pipeline Valves » The Piping Engineering World
