Checking One-way warning valve
The one-way fire alarm valve has a grooved double check valve that ensures positive water flow for alarm operation and is designed for installation in a sprinkler system. Its external bypass system prevents false alarm under the condition of all supplied pressures.
The warning one-way valve allows installation under constant and variable pressure requirements. The operation of one or more automatic sprinklers causes water to flow in the sprinkler system and also causes the alarm valve to open and as a result, the electric and mechanical alarm alarm is activated.
Wet systems are the most common type of automatic fire extinguishing system, in this system, water with a certain pressure is in the piping network and behind the sprinkler, and as soon as the bubble of one or more sprinklers is broken, due to the pressure drop, the one-way valve is opened. And the water sprays on the fire with pressure.
Among the capabilities of this system are high speed, high reliability and no delay in performance. At the same time as the fire extinguishing operation, the mechanical alarm system is activated and it is possible to connect this system to the fire alarm and electrical alarm system.
