ZSFM diaphragm deluge alarm valve

Diaphragm type deluge alarm valve
Product Introduction
Diaphragm type deluge alarm valve can be installed vertically or horizontally, its specifications range from By applying pressure, you can reset the deluge system or pre-action system.
In addition to the diaphragm structure, the diaphragm deluge alarm valve has no valve disc and connecting rotating parts. The valve is coated with anti-corrosion coating inside/outside. The valve is made of ductile iron and can be installed in industrial areas with corrosive environments and outdoors.
Product Description
The deluge valve group should be installed in an obvious position that is safe and easy to operate. The height from the indoor floor should be
. The distance between both sides and the wall should not be less than the distance between the surface and the wall. The distance should not be less than the indoor floor where the alarm valve group is installed and there should be drainage facilities.
Valve installation
) Before installation, the pipeline must be flushed and dirt and debris removed until clean water flows out.
) During installation, transportation or lifting, force should be applied on the necks of the two flanges. It is strictly forbidden to apply force on pipeline accessories to prevent deformation, leakage and damage.
) This valve should generally be installed vertically on the pipeline with the arrow pointing upward. When it must be installed horizontally, it should be stated in advance when ordering. The installation position should consider sufficient space for repair and maintenance.
) All drain outlets of this valve should be connected to the drainage pipes with galvanized pipes and hoses of suitable diameters.
) The solenoid valve should be connected to the electric control cabinet through the control module, voltage.
) When installing the hydraulic alarm bell, you should remember that the small opening is the water inlet, install it horizontally, and the entrance is the drainage outlet, install it vertically, and the galvanized pipe is.
) Firefighting butterfly valves with signals of the same caliber should be installed at both ends of this valve to facilitate control and maintenance. Our company can provide you with qualified manual and worm gear rotating signal butterfly valves.
