AD Series Automatic Manifold System:

The AD series automatic duplex manifolds are designed for applications requiring a constant and uninterrupted supply of compressed gas. This control will allow changeover from one bank to another automatically, provided a sufficient differential is maintained between the two primary regulators. After changeover, a simple manipulation of four master valves reverses the "service" and "reserve" banks. A line regulator is required to eliminate the changeover pressure differential and maintain a constant line pressure. An alarm can be added to signal changeover from "service" to "reserve" bank by adding items WME-4-9 pressure switch, SWM-1-97 orificed adaptor, WMS-9-25C power supply box and BIA-3 remote audio visual alarm.

• Model RM (or RDM for oxygen) (pressure compensated regulator), adjustable delivery pressure 20-160 PSIG. Optional equipment is available upon request for higher delivery pressures up to 3,000 PSIG.
• 24" Flexible Stainless Steel braided Teflon® lined pigtails with check valves. Check valve is at header end of pigtail except Oxygen. Note: Helium and Hydrogen manifolds are shipped with synthetic fiber braided pigtails. Vertical crossover and staggered styles include equal quantities of 24" and 36" pigtails.
• Individual header valves at each cylinder location (units with 4 cylinders or larger - all gases except Oxygen). Oxygen units shipped with check valve outlets in place of header valves to provide added safety from "heat of recompression".
• Acetylene manifolds shipped complete with a dry falshback arrestor, separate flash arrestor with check valve on each pigtail and connecting piping.
• Optional safety kits (flash arrestor and relief valve) available for Liquefied Fuel Gas manifolds.
