This custom-built manifold contains three separate pneumatic circuits.
The Pneumadyne’s engineering team redesigned the circuit into a block assembly that eliminated 25 individual components. The device included three pressure transducers that provide an electronic interface for the measurement of system pressure; push-to-connect fittings that simplify tubing connections and system installation; a built-in, quick-reaction air reservoir; and four solenoid valves to control cylinders and other functions within the circuit.
The design also included a custom, double-acting rolling diaphragm cylinder with integral position feedback. The cylinder had to function without “stiction” or hesitation at a pressure differential of only 1.5 psi.
The block assembly met the application requirements, eliminated numerous potential leak points, and reduced the amount of time needed to plumb the pneumatic circuit.

Another equipment manufacturer faced the challenge of reducing the size of a pneumatic system to fit the space constraints imposed by operating-room equipment that had already been designed. Complicating matters, several components within the device had to withstand autoclaving sterilization.
Pneumadyne engineers sought to combine the functions of several individual operatory devices into a single package. The goal was to reduce the space needed for three separate pneumatic circuits while meeting specific flow and pressure demands.
To solve the problem, the engineers developed an integrated manifold block that houses the three separate circuits and meets the space constraints of the customer’s equipment. This multifunction assembly, in turn, let the customer replace several devices within the operatory.
The design included:
• A precision regulator preset at 2 psi controls pressure in one circuit.
• A regulator preset at 7.5 psi supplies pressure to a water chamber.
• A valve housed within a plastic cap controls water flow.
• Four pressure transducers measure system flow and pressure.
• Five oxygen-cleaned solenoid valves.
• Push-to-connect fittings that ease tubing connection and system installation.
• Two relief valves to vent overpressure.
Special tests ensured that the device met the required flow and pressure specifications.
