Firefighting systems usually use different types of valves to manage how water or other fire-extinguishing materials flow. The valves control the flow of water, foam, or other fire-suppressing agents. These valves are an important part of systems like sprinklers, fire hydrants, and hose reels. Without them, water might not reach the fire in time, or it might not flow through at all.
Types of Valves
There are several kinds of valves used in fire safety, and each one has a specific job in keeping people and buildings safe. Maintaining a reliable valve stock, like the valve stock from Orseal, is important to make sure that the fire safety systems can be quickly repaired. Using the wrong fire valve can be very dangerous.
1. Gate Valves
Gate valves are used to fully close or open the water flow in a fire protection system. They do not adjust the flow but just turn it on or off, and are common in sprinkler systems.
2. Butterfly Valves
Butterfly valves also control water flow. They are smaller and lighter than gate valves and are often used in large buildings.
3. Check Valves
Check valves stop water from flowing in the wrong direction. They are important in keeping the system working properly and avoiding damage. They open when water flows the right way and automatically close if it starts flowing backwards.
4. Pressure Relief Valves
These valves help control the pressure in the system. If the water pressure gets too high, the relief valve opens to release some of the pressure, preventing damage to pipes and equipment.
5. Alarm Valves
Alarm valves are used in wet-pipe sprinkler systems. When the valve opens during a fire, it also triggers an alarm to warn people that the sprinklers have been activated.
6. Deluge Valves
These valves are used in systems that need to release a lot of water all at once, like in high-risk areas such as power plants or chemical storage rooms. When a fire is detected, the deluge valve opens and floods the area with water.
