1. ZSFG Deluge valve is a one way valve, which is opened by wet method, dry method, electric method or manual method, can make the water automatically flow into sprinkler system in one way and at the same time make the alarm. It is widely used in sprinkler system, pre-acting system, water spray projecter system or water curtain system.
2. Sprinkler system mainly consists of deluge valve, automatically open and control system, tube web, open sprinkler and water supply system. It is used for dangerous fire, more combustibles, huge heat generated, big fire and spread rapidly fire with inflammable and explosive places, and the required temperature is no less than 4 degree centigrade. Such as Alcohol solvent products factory, the place of flammable liquid spray operation, Chemical goods warehouse and stage grape
3. Pre-acting system mainly consists of deluge valve, wet valve, automatically open and control system, tube web, close sprinkler and water supply system.
