DUYAR Dry Pipe Alarm Valve

Description

DUYAR Y-4015 Dry Pipe Alarm Valve is a differential dry pipe alarm valve designed for automatic fire sprinkler systems exposed to freezing temperatures. Holds back high supply water pressure using lower system air/nitrogen pressure. Upon sprinkler activation, the rapid release of air opens the main clapper to deliver fire suppression water immediately while triggering system alarms. Ideal for unheated warehouses, parking garages, and cold storage facilities. Key Features: • Size Range: DN100 (4"), DN150 (6"), and DN200 (8"). • Pressure Rating: Working pressure up to 300 PSI (20.6 bar). • Maintenance Friendly: External reset function allows quick resetting without taking off the bonnet cover. • Installation: Designed specifically for vertical installations in wet-to-dry riser setups. Full technical specifications and dimensional details are available in the attached datasheet. We can supply to all governorates in Iraq
