1.description

The electric automatic exhaust valve group consists of automatic exhaust valve, gate valve, fire-fighting solenoid valve and pipe fittings. It is used in dry and pre-action systems, installed at the top, end and water-filling turns of the system piping.

When the system is filled with water and exhaust, the system's gas-water conversion time is accelerated to ensure that the system will extinguish the fire in the early stage of the fire, shortening the response time; reducing the exhaust at the blasting nozzle during the fire to help the fire, and improving the efficiency and reliability of the system.
