Reliable Ddx/wd Wet/dry Pipe Valve System

We are providing Reliable DDX/WD Wet/Dry Pipe Valve System to our clients with the following features:
1. In reduced temperature area systems, lower air pressure decreases the possibility of ice plugs, which could impede or prevent the flow of water to sprinkler heads in the event of a fire.
2. Lower air pressure (volume) will enable smaller capacity, lower cost dehydration equipment when it is required.
3. Lower air or nitrogen pressure can reduce water delivery time when the system actuates, and in some cases, may eliminate the need for an accelerator.
4. Lower pressure requirements make the use of dry nitrogen gas, instead of air, practical even on larger systems. Resulting benefits include a lower than air dew point, which minimizes ice plugging of system lines, and enhances a user friendlinessa during installation and operation.
5. System maintenance is simplified since priming water is not required and the Model DDX-W/D Valve can be reset externally without cover re- moval. This is accomplished by turning the exter- nal reset knob at the rear on the Model DDX-W/D Valve. This feature provides a signifi- cant system-restoration time advantage. The Model DDX-W/D Wet/ Dry Valvea s trim set provides all of the necessary equipment for connections to the pushrod chambera s inlet and outlet ports, the 50mm (2a ) main drain, alarm devices, air supply, water supply, and required pressure gauges.
