This final iteration of the manifold includes deeper cuts underneath to allow for easier flow, 30 degrees cut into the inner diameter, increased inner diameter, as well as the chamfers around the edges to ensure the safety of the operator when handling it.
Valve
Valve
The final model of the valve includes a block of PTFE threaded as a valve housing, and uses a machined stainless steel cylinder to control the flow of the exhaust. The shaft is also secured using an e-ring as well as the coupler in the back. This simplified version allows for more affordable and quick machining.
Mounting Bracket
Mounting Bracket
The mounting of the valve assembly includes a machined aluminum block tight fitted for the valve and the actuator, as well as the plates to secure the parts from the top. The plates include through holes for both valves as well as the screws for securing the plates.

Manifold V3
Manifold V3
This is an early iteration of the V4, where the block was not cleaned off for less material.
Manifold V4
Manifold V4
The manifold design includes multiple aspects that have been inspired by the previous iterations of the manifold. The top connects to the PTFE tubing with a 4mm outer diameter. The leader redirects the tube towards the clear path out of the contactor area. The bottom part is bored to redirect the air from the contactors to the tube, and the side includes a tapped 4-40 hole for the set screw.
Manifold V1
Manifold V1
This initial redesign included a leader in order to connect a 4mm outer diameter PTFE tube. The bottom side is bored out to redirect the flow. It also extended the base in order to make sure there is enough extension outbound but this manifold was not able to clear the PTFE tube from the handlers.
Manifold V2
Manifold V2
The second redesign includes a far extension for the tube to pass all obstacles. This design not only requires a more costly manufacturing process but also two models for each side of the 2x8 array since each side has different longitudinal clearances.
Valve

Valve V1
Valve V1
The initial design of the valve consisted of two PTFE pieces screwed together with a stainless steel shaft machined as the butterfly mechanism.
Valve V2
Valve V2
The next iteration of the valve moved onto a simpler shaft design, as well as reducing the machining process. Since this part a modified version of the V1, it still includes top and bottom PTFE housing.

This manifold was given to us by Cohu Inc. in order to design our product based on the size constraints. This part, however, only creates a block where the flow is redirected to the sides.
