A manufacturer of medical equipment invited Bimba to evaluate a new trauma device that they were developing. They had mocked up the pneumatic system using individual components from various competitors and asked Bimba to suggest improvements for their system.


  • Design a circuit that would fit inside the customer’s existing equipment mold
  • Decrease the time required to assemble and install the circuit
  • Meet flow and pressure requirements at a pump pressure of 7 psi
  • Provide pressure sensing feedback to the equipment's computer
  • Eliminate potential leak-points


Pneumadyne Custom ValveBimba's Sales and Engineering teams designed the complete circuit, including the actuators, and proposed an integrated solution that reduced the number of components from 29 to just 4. Pneumadyne's integrated solution eliminated numerous potential leak-points and reduced the amount of time needed to plumb the pneumatic circuit.

In addition to the block assembly, Bimba also designed and built the unique double acting rolling diaphragm cylinder with position feedback shown here. This cylinder had to function without hesitation at 1.5 psi.


  • Reducing components saved customer money
  • Push-to-connect fittings for quick installation
  • Built-in reservoir for quick reaction
  • Four solenoid vavles control cylinder and various functions within the circuit
  • Eliminated potential leak-points

Other applications:

  • Dispensing
  • Packaging
  • Material Handling
