Maximum pressure - Pressure describes the amount of force exerted on the system by the contained fluid. Most compressed gases will not exceed 2,000 to 2,640 pounds per square inch gage (psig), but some can reach pressures of 6,000 psig. Matching the performance specifications for manifolds and manifold systems to the needs of the application is important for proper selection. Performance specifications, port and valve specifications, components and circuit style, and applications are all important parameters to consider when searching for manifolds. Gas cabinets and distribution systems also contain manifolds as flow components which connect compressed gas cylinders and eliminate the need to repeatedly handle regulators during cylinder change-out.

Instruments - Pressure gauges, switches, and other devices used to perform various system functions involving measurement. Valves - Used to control flow through the ports of the manifoldįlexible connectors - Braided connectors that bend and flex to attach containers to manifolds or manifolds to fixed equipment. This helps extend seal life and prevent leakage. Pipe or tube - Vessels used to transport the fluidįittings - Tees, elbows, crosses, plugs, and other parts that fit pipe to manifolds.Įxpansion chambers - Allows for a certain percentage of expansion in the piping line to prevent pressure increase in the system. Manifold systems are more complex, and incorporate a number of other components: Gas enters and exits through one or more ports as appropriate for an application. One piece manifold devices are simple in construction. A manifold is a fluid or gas distribution system or device that serves to bring many junctions into one place or a single channel into an area where many points meet. Manifold systems range from simple supply chambers with several outlets to multi-chambered flow control units including integral valves and interfaces to electronic networks. Complex pneumatic and hydraulic circuits can utilize manifolds and manifold systems with interfaces to sophisticated electronic networks.
