Dry Valve Manufacturer

The dry powder valve is an important component of the dry powder fire extinguisher, which can control the release and spraying of the dry powder fire extinguishing agent. Valves are generally composed of valve bodies, valve stems, valve cores, sealing rings, and other components. When in use, it is necessary to open or close the valve by operating the valve stem to control the spraying of dry powder fire extinguishing agent.

Dry Valve Industry Knowledge Extension
Basic introduction to dry valve system?
A dry valve system is a device used in automatic fire suppression systems. It is often used in cold climates or conditions prone to freezing to prevent water pipes from freezing. Dry valve systems are different from common wet fire automatic fire extinguishing systems. Wet systems retain water in pipes so that in the event of a fire, it can be released immediately to extinguish the source of the fire. Under normal circumstances, what is stored in the pipeline of the dry valve system is not water, but compressed air or nitrogen. When a fire alarm is detected, the automatic fire alarm system sends a signal to the drying valve, which then opens, allowing compressed air or nitrogen to enter the pipe and release water for fire extinguishing.
What are the application areas of the Dry Valve system?
The main advantage of the Dry Valve system is that it can be used in cold environments because there is no water in the pipes and will not freeze, thus ensuring that a source of firefighting water is available when needed. This is useful for protecting cold storage, parking lots, underpasses and other locations that may be affected by cold weather. Dry valve systems are often used when a submersible pump or other water source cannot be easily maintained to ensure system reliability.
Freezing warehouse: In a refrigerated warehouse, the temperature is very low. If a conventional wet automatic sprinkler system is used, the water in the water pipes can easily freeze, thus hindering the normal operation of the fire emergency extinguishing system. The Dry Valve system prevents water from freezing in pipes and only supplies water to the system when a fire is detected to ensure fire suppression effectiveness.
Cold storage: Similar to refrigerated warehouses, Dry Valve systems are also used in cold storage to prevent water pipes from freezing while providing reliable fire extinguishing protection.
Refrigerated ships and port facilities: These environments often require cryogenic storage and transportation, so Dry Valve systems are also commonly used on refrigerated ships and port facilities to ensure that water pipes do not freeze in the event of a fire.
Freeze-proof underground parking: Underground parking lots usually require fire protection systems, but since water pipes tend to freeze in cold climates, the Dry Valve system is an effective option to ensure reliable water supply in the event of a fire.
Cooling Towers and Industrial Facilities: Some industrial facilities may require the use of Dry Valve systems, especially in areas with lower ambient temperatures.
In summary, the main areas of application for Dry Valve systems are where working in low temperature conditions is required, to ensure that fire protection systems can operate reliably when needed, while preventing water pipes from freezing.
