An air valve assembly is a built-up pneumatic component group that controls the flow of compressed air within a machine or system. It can include valves, manifolds, fittings, wiring, and related components assembled together so they arrive organized and ready for installation.
A valve stack and a valve manifold are closely related terms that are often used interchangeably. In most industrial applications, both refer to a grouped assembly of pneumatic valves mounted together to control multiple air functions from one organized point, helping reduce plumbing, simplify wiring, and save space.
FRL stands for filter, regulator, and lubricator. It is an air preparation assembly used to clean compressed air, control pressure, and, when needed, add lubrication before air reaches downstream pneumatic components.
The right air prep assembly depends on your pressure requirements, flow needs, filtration level, environment, and whether your application needs accessories like shutoff valves, lockout capability, gauges, drains, or lubrication. Many buyers start with a schematic, BOM, or photos of the current setup to identify the right configuration.
Yes. Custom pneumatic valve manifold assemblies can be built around your application requirements, including valve count, port size, electrical setup, communication protocol, fittings, labeling, and kitting needs. This is often the best option when you want a cleaner install and less assembly work in-house.
PennAir builds air valve assemblies, valve stacks, and FRL air prep assemblies for OEMs, machine builders, and industrial plants that need pneumatic sub-assemblies delivered ready for installation.
If your team is spending too much time building, sourcing, labeling, or troubleshooting pneumatic assemblies in-house, PennAir can help reduce bench work and keep projects moving.

Need a valve stack built to your requirements instead of shipping loose parts to your team for assembly?
PennAir can build custom air valve assemblies and valve stacks based on your station count, porting, electrical requirements, and installation needs. That includes valve manifold assemblies designed to arrive organized, tested, and ready to mount.
Typical valve stack assembly support includes:
This is a strong fit for OEMs, machine builders, packaging equipment, automated systems, and plants that want cleaner layouts, faster installation, and less troubleshooting in the field.
PennAir also builds FRL assemblies and air preparation assemblies that help protect downstream components, stabilize air pressure, and simplify point-of-use installation.
Whether you need a standard filter regulator lubricator assembly or a more application-specific air prep package, PennAir assembles units around your pressure, filtration, drain, and accessory requirements.
Typical FRL / air prep assembly support includes:
This is a good fit for production equipment, pneumatic drops, machine-level air prep, and general industrial automation applications where uptime and consistency matter.
