< Automatic exhaust valves are specially designed for fire protection systems such as wet, wet-dry alternating, pre-action, circulation, foam spray, and foam storage tanks in automatic sprinkler fire extinguishing systems. Installed on the top of the system to prevent air blockage and air blockage when the system is filled with water and exhausted. After it is filled with water, it automatically closes the air outlet and automatically opens the air suction when draining water for system maintenance to prevent negative pressure deformation and damage to the pipe network.
< The electromagnetic exhaust valve group is used in dry and pre-action systems and is installed at the top, end and water-filled turns of system pipes.
When the system is filled with water and exhausted, it speeds up the gas-water conversion time of the system to ensure that the system releases water to extinguish the fire in the early stage of the fire. It shortens the response time and reduces the exhaust gas at the blasting nozzle to fuel the fire during the fire, improving the system's fire extinguishing efficiency. Efficiency and reliability.
< Product Features:
< Its exhaust volume is much larger than similar exhaust valves on the market, it has a long sealing life and high reliability of repeated opening and closing. The float and hinge mechanism are made of stainless steel.
