air release valve in fire fighting system 

A fire extinguisher valve is a crucial component of a fire extinguisher. It is typically located on the top or side of the extinguisher and is used to control the flow of the extinguishing agent, such as water, foam, or dry chemical, when the extinguisher is activated. The valve is designed to be easily operated by hand and typically includes a lever or handle that can be squeezed or pulled to release the extinguishing agent. When the valve is opened, the agent is expelled through the nozzle or hose of the extinguisher, allowing it to be directed towards the fire. The valve also includes a mechanism to control the pressure and ensure a steady flow of the extinguishing agent.Red Fire Extinguisher Valve
