Steam sterilization equipment is often discussed in terms of cycle parameters such as heat, pressure, and dwell time. Those are the outcomes the system must deliver.
Behind those outcomes, however, is a less visible requirement that has a major impact on performance and maintainability: coordinated pneumatic routing.
Marsh Medical’s MD2700 steam sterilization application study highlights a design reality many OEM teams face. Sterilization systems are not driven by a single pneumatic event. They depend on a sequence of valve actions that must occur in the right order, at the right time, and across different parts of the machine.
Steam sterilization cycles rely on coordinated valve actions
In sterilization equipment, pneumatic functions may be responsible for opening and closing valves, shifting flow paths, managing exhaust stages, and isolating sections of the system during different cycle phases. These actions can happen in sequence and in parallel, depending on the machine design.
That creates an architectural challenge.
As systems grow in capability, the pneumatic layout can become harder to manage. Different sections may operate at different pressures, and supply and exhaust paths may need to be controlled independently throughout the cycle.
The result is often a pneumatic network that works, but becomes increasingly difficult to install, troubleshoot, or adapt.
Where traditional point-to-point layouts create friction
The study calls out a common issue in sterilization equipment design: traditional point-to-point pneumatic layouts can quickly become complex, with more tubing, wiring, and individual valve assemblies than teams initially expected.
That complexity can affect more than packaging space. It may also increase:
• Installation time during build
• Troubleshooting effort during service
• Difficulty when updating or expanding equipment
• Overall system rigidity as platform requirements change
For OEMs, this becomes a scalability problem. A layout that is manageable early in development may become inefficient as features, zones, or automation requirements increase.
How the MD2700 changes the pneumatic design approach
The MD2700 Medical Manifold is presented in the application study as a centralized pneumatic routing and sequencing platform within steam sterilization equipment. Instead of functioning as a pressure regulator, it serves as the routing layer that directs where pressurized air, or steam-actuated control air, is sent based on system commands.
By consolidating multiple solenoid valves into a modular manifold, the MD2700 allows OEMs to execute complex valve sequences from a centralized location. The study notes that different valve slices can be assigned to functions such as steam admission, exhaust routing, door interlocks, and auxiliary operations, while also supporting multiple pressure zones within the same manifold.
In practical terms, this supports a cleaner pneumatic architecture and a more organized approach to sequence control.
One of the strongest takeaways from the study is not just about current performance, but future adaptability.
As steam sterilization equipment moves toward higher throughput, tighter cycle validation, and greater automation, OEMs need pneumatic systems that can be reconfigured without redesigning the entire network. The MD2700 is positioned as a scalable pneumatic backbone that helps make that possible.
Its modular approach supports:
• More organized valve actuation
• Reduced pneumatic system complexity
• Precise sequence execution across cycle stages
• Easier adaptation as platforms evolve over time
A smarter question for sterilization equipment design teams
When evaluating pneumatic architecture for steam sterilization systems, it helps to ask more than “Can this layout run the cycle?”
A better question is:
“Will this routing strategy still be manageable when the platform adds functions, zones, or automation requirements later?”
That is where centralized, modular pneumatic routing can become a real design advantage.

Common Questions About the MD2700 and Steam Sterilization Pneumatic Routing
Why is pneumatic routing important in steam sterilization equipment?
Pneumatic routing is important because steam sterilization systems rely on coordinated valve actions across different cycle stages. Air routing may control steam admission, exhaust paths, door interlocks, isolation points, and auxiliary functions that must operate in the correct order.
What challenges do traditional point-to-point pneumatic layouts create?
Traditional point-to-point pneumatic layouts can become complex as sterilization systems add more valves, zones, tubing, wiring, and automation requirements. This can increase installation time, complicate troubleshooting, reduce layout flexibility, and make future equipment updates more difficult.
How does the MD2700 support steam sterilization systems?
The MD2700 Medical Manifold supports steam sterilization systems by centralizing pneumatic routing and valve sequencing. It consolidates multiple solenoid valves into a modular manifold, helping OEM teams organize pneumatic control from one structured platform.
Is the MD2700 a pressure regulator?
No. The MD2700 is not a pressure regulator. It functions as a pneumatic routing and sequencing platform that directs pressurized air, or steam-actuated control air, to the correct valve functions based on system commands.
How can centralized pneumatic routing improve sterilizer serviceability?
Centralized pneumatic routing can improve serviceability by reducing scattered tubing runs, individual valve assemblies, and hard-to-trace pneumatic paths. A more organized manifold-based layout can make installation, troubleshooting, maintenance, and future updates easier for service teams.
Can the MD2700 support multiple pressure zones?
Yes. The MD2700 can support multiple pressure zones within the same manifold architecture. This helps OEMs manage different pneumatic functions across a sterilization cycle while keeping the control layout cleaner and more scalable.
Why does modular pneumatic routing matter for future sterilizer platforms?
Modular pneumatic routing matters because sterilization equipment may evolve with added functions, automation requirements, cycle stages, or control zones. A modular manifold approach can make it easier to adapt the pneumatic architecture without redesigning the entire system.
How does Marsh Medical support steam sterilization pneumatic control applications?
