# Where are Gate Valves Used? Areas of Use and Application Guide
Gate valves are a type of industrial valve used to **completely open or completely close** the flow of fluid in a pipeline. Flow is controlled by the up and down movement of the slide inside the valve.
Gate valves have a very wide range of applications, from water systems to fire systems, industrial facilities to power plants, because they create minimal obstruction in the flow path when fully open, provide low pressure loss, and can be used in large-diameter pipelines.
Gate valves are generally preferred for **opening and closing the line, not for adjusting flow rate.** They are an effective and reliable solution for lines that need to operate in a fully open or fully closed position for extended periods.
## 1. Drinking Water Networks
One of the most common areas of use for gate valves is in city and building **drinking water distribution systems.**
They are used to separate specific sections of main water lines, to shut off the line during maintenance, and to control the network.
Main application points:
* Municipal main water networks
* City water distribution lines
* Building entrances
* Water tanks
* Pumping stations
* Water distribution centers
* Industrial water systems
Especially elastomer-seated gate valves are frequently preferred in water systems due to their leak-proof properties and ease of use.
## 2. Municipal Water Distribution Lines
Pipe systems used in municipal infrastructure can reach lengths of kilometers. It is impossible to shut down the entire network in case of any malfunction or maintenance.
Therefore, the line is divided into specific sections, and the necessary section is isolated using gate valves.
For example, when a pipe malfunction occurs in a section, the relevant gate valves can be closed, stopping the water flow only in the faulty line.
This system:
* facilitates maintenance operations,
* reduces the impact area of water outages,
* increases network control,
* allows for faster response to malfunctions.
## 3. Fire Suppression Systems
Gate valves are among the important equipment of fire suppression systems.
Especially;
* Fire pump lines,
* Fire hydrant systems,
* Sprinkler installations,
* Fire water tanks,
* Building fire risers,
* Industrial fire lines
These systems can be used in fire systems.
Maintaining the correct position of valves in fire systems during normal operation and reliably isolating the line when necessary is of great importance.
In some applications, **rising stem gate valves (RS&S)** are preferred. Thanks to the rising stem structure, it is easier to see from the outside whether the valve is open or closed.
## 4. Fire Hydrant Lines
Gate valves can be used in the main water lines supplying above-ground and underground fire hydrants.
To prevent the main network from being completely shut down during hydrant maintenance or replacement, an isolation valve can be used before the hydrant connection.
In this way, only the relevant hydrant line is deactivated.
Especially;
* Factories,
* Organized industrial zones,
* Warehouses,
* Logistics centers,
* Shopping malls,
* Hospitals,
* Airports
These types of applications are important in large areas such as these.
## 5. Wastewater Systems
When appropriate materials and design are selected, gate valves can also be used in some wastewater and treatment applications.
Areas of use include:
* Wastewater treatment plants,
* Sewage pumping stations,
* Treatment plants,
* Industrial wastewater systems,
* Process water lines
However, if the fluid contains a high amount of solid matter, the type of valve to be used must be determined according to the system conditions.
## 6. Water Treatment Plants
Drinking water and industrial water treatment plants contain numerous pipelines and equipment.
Isolation valves are used to allow filters, pumps, tanks, and process equipment to be separated from the system during maintenance.
Gate valves;
* They can be used in filter inlets and outlets,
* pump lines,
* storage tanks,
* main distribution pipes,
* process water lines.
## 7. Pump Stations
Gate valves are also widely used in pump systems.
Isolation valves may be present in the inlet or outlet lines to allow the pump to be disconnected from the system during maintenance or replacement.
In a typical pump line, depending on the system requirements;
**Gate Valve → Pump → Check Valve → Gate Valve**
such a configuration can be created.
Here, gate valves are used for line isolation, while check valves prevent the fluid from moving in the reverse direction.
## 8. Industrial Facilities
Gate valves can be used in many industrial production facilities.
For example:
* metal industry,
* machine manufacturing,
* automotive plants,
* plastics industry,
* textile plants,
* food production plants,
* paper mills,
* chemical plants
These can be used in auxiliary facilities and process lines in businesses such as these.
Here, valve selection should be based not only on pipe diameter but also on:
* fluid type
