Fire valves are critical components in fire protection systems, controlling the flow of water to fire suppression systems like sprinklers and hose reels. Here's a breakdown of key information about fire valves:  
Types of Fire Valves:
Gate Valves: Used to completely shut off or allow the flow of water. They are not ideal for throttling flow.  
Butterfly Valves: Used for both shut-off and flow regulation. They are compact and easy to operate.  
Ball Valves: Provide quick shut-off with a 90-degree turn.  
Check Valves: Allow water to flow in one direction only, preventing backflow.  
Pressure Reducing Valves: Maintain a consistent water pressure in the fire suppression system.  
Alarm Check Valves: Used in wet pipe sprinkler systems to trigger an alarm when there is a flow of water, indicating a possible fire.  
Landing Valves: Located in stairwells of buildings, these valves allow firefighters to connect hoses to the standpipe system.  
Applications of Fire Valves:
Sprinkler Systems: Control water flow to sprinkler heads.  
Standpipe Systems: Provide water to fire hoses in high-rise buildings.  
Fire Pumps: Isolate pumps for maintenance or testing.
Fire Hydrants: Control water flow from the hydrant.
