Description
The Reliable Model DDX-LP Dry Pipe Valve System is a hydraulically operated, mechanical latching clapper-type valve designed for use as a primary control valve in a dry pipe system. The pneumatic system pressure when using the Model DDX-LP valve can be set substantially less than conventional differential style dry valves.
All sizes of the Model DDX-LP valve may be equipped with the Reliable Model B1 Accelerator (P/N 6501200019; ordered separately). The accelerator operates as an exhauster to hasten the operation of the dry pipe valve.
