Protecting residential, commercial, factory, and corporate buildings from fire is one of the most important things to protect financial safety and personal safety. Therefore, building a fire protection system is very important. The fire fighting system includes smoke detection, fire extinguishing, sprinkler fire and other cooperative equipment. Among them, the valve could help to water supply in the fire protection system, so it is also very important to choose the right valve.
In this article, we will introduce you to COVNA valves that can be used in fire protection systems. Hope to help you choose the right valve.
Fail Open Valves
Fail open valve means the valve will auto-open when power is off.
If a fire occurs suddenly, the circuit may be interrupted. At this time, the fail-open valve will be open then the water could be transported and extinguish the fire.
Recently we received inquires about the fail-open valve for the fire protection system. The Auto return normally open actuated butterfly valve is recommended.
Under normal conditions, the valve is closed. However, in the event of a failure, the valve will automatically open so that the water can transport normally.
The check valve only allows one-way flow, it can prevent the backflow of water, thereby protecting the device.
