There are many types of gate valves, such as full bore gate valves, parallel disc gate valves, solid wedge gate valves, flexible wedge gate valves, split wedge gate valves, vertical stem gate valves and non-vertical stem gate valves.

Gate valves allow the user to control the flow pressure rather than simply closing or opening it.

Gate valves are used to shut off the flow of media in piping systems and are widely used in drinking water, water supply and drainage, sewage treatment, irrigation, air conditioning, fire protection, and chemical energy.

Cast iron gate valves are used in commercial and industrial applications. Typical services include: hot and cold water, HVAC, steam, gas and other general utility services.

Gate valves are widely used in pipelines that carry media. Gate valves can be classified as wedge gate valves, flat gate valves, and parallel double gate valves according to the form of valve seat. The product can have a longer service life.

Gate valves are very reliable in shutting off water supply. They are commonly used as shut-off valves for main water supply lines and branch water supply lines, although ball valves are gradually becoming more popular in these applications.

The most common causes of gate valve failure are wear and corrosion. Over time, gate valves tend to wear out. Corrosion can cause the disc to become stuck in the open or closed position.

Gate valves are not suitable for throttling volumes. Flow control is difficult because the design of the valve is such that a partially open gate with fluid flow can cause severe damage to the valve.

Gate valves can be divided into two main types: parallel and wedge. Parallel gate valves use a flat gate plate between two parallel seats. The popular type is the knife gate valve with a sharp edge at the bottom of the gate.

Gate valves are an energy efficient valve option because the direction of movement or the gate is perpendicular to the direction of media flow. As a result, less power is consumed to open or close a gate valve than a globe valve.

The gate valve is the most common valve used in water supply systems. It represents a linear motion isolation valve with the function of stopping or allowing flow.

The gate valve consists of three main parts: the body, the bonnet and the valve internals. The body is generally connected to other equipment by flange, threaded or welded connections.
