Hydraulically Controlled Deluge Valve:
This type of system in UL Deluge Valves are suitable for wet pilot lines with closed fusible plugs. Provided with boosted local opening, it is recommended for systems with elevated fusible plugs. The deluge valves latches open in response to hydraulic pressure drop in the wet pilot line.
Electro – Hydraulically Controlled Deluge Valve:
This type of deluge valve is solenoid (electrically) operated with hydraulic (line fluid) actuated. The deluge valve opens in response to an electric signal which drains the cover chamber of pilot and main valve, which allows the to fully open.
Pneumatically Controlled Deluge Valve:
This type of deluge valve opens up in response to pneumatic pressure drop in the dry pilot line. This system is suitable for dry pilot lines with closed pneumatic pressure drop in the dry pilot line.
Electro-Pneumatically controlled Deluge Valve:
This type of deluge valve has electric and Electro Pneumatic device for detection. The deluge valve opens in response to an electric signal and/or pneumatic pressure drop in the dry pilot line.
Test and Alarm Trim with Sprinkler Alarm:
This trim is supplied with the sprinkler alarm bell, which rings on actuation of deluge valve. A test valve is provided to test the normal operation of the sprinkler alarm bell.(water motor gong)
