And I mean this in a literal sense: With a click, the wall becomes the floor and a new world opens up to explore.įrom there, I continue to play with gravity to solve the game’s puzzles. I have to shift perspective by activating a different plane, which changes my view. My expectations of how things are supposed to work are broken down by the game’s mechanics.

Mounting: Ensure that the manifold is either brand specific mounting or adheres to the correct ISO standard and corresponding size.Ī pneumatic manifold symbol, as seen in Figure 9, is a perpendicular intersection of two lines inside of a square.Pressure rating: Ensure that the manifold can handle enough pressure for all of the connected valves and if there is a need for additional pressure post manifold.Material: Material depends on budget and must be compatible with the media in the system.Number of valve ports: The number of the valve's ports must match the number of the manifold's ports.If it is unknown and could change, a modular design may be easiest. Number of valve stations: If a set number of valves are known, then a single-piece design manifold with a set number of valve stations is a good solution.If a manifold is deemed to make the application simpler and easier, then it is easy to select. As they are modular, additional leakage paths are available but all blocks and plates are equipped with o-rings and seals to prevent leakage.įigure 8: ISO 15407 sizes for ISO 02 and 01. Divider plates have the ability to block a flow passage by plugging it, and spacer plates simply adjust the dimensions between basic modules when a larger sized valve is used and additional space is required. The interconnecting plates can divert the flow from one passage to the other between the basic modules. These plates are usually installed in-between basic modules and each serve their own function. They consist of basic building blocks as well as interconnecting, divider and spacer plates. As each modular pneumatic manifold holds one valve, additional blocks can be added or subtracted for easy modification, maintenance, and mixture of different valve sizes. Modular block manifolds are designed as their name suggests, to be modular, and can be seen in Figure 3. For a manifold ported manifold, the valve outlet is on the bottom so the manifold has another media route through the side of the manifold. A body ported manifold, as seen in Figure 2, has the valve outlets on top of the valve. Single-piece pneumatic manifold blocks can also be body ported or manifold ported. Blanking plates are available to close off ports. They need to be specified for how many ports (for example, for a 3/2-way or 5/2-way valve) and how many valves. Typically, 2-10 pneumatic solenoid valves can mount on a single-piece manifold. However, due to being drilled, air manifold blocks do have design limitations as the flow path must be straight. Since they are single-piece designs, they have minimal leakage paths making them a robust solution even for high pressure applications. Figure 2 shows an example of a single-piece manifold design. Most common, is a drilled metal-block made out of steel, aluminum, or cast iron to create the required flow paths and ports. This allows the manifolds to be used with valves manufactured by others. Other manifolds adhere to standardized mounting patterns, like ISO 5599 and ISO 15407. Some manifolds can also be brand specific, meaning they can only be used with that specific brand’s valves. Manifolds come in different pressure ratings, number of stations, port sizes, flow rates, functions and housing materials. Manifolds in pneumatic systems are used for applications that require numerous valves, such as, mobile machinery and heavy industrial equipment. The shorter path flows resulting from using air manifolds reduces pressure drops and overall system energy consumption. The compact pneumatic manifold design lowers the costs of valve installation by eliminating a large portion of tubing in the system, which results in minimal system complexity, quicker dismantling, less leakage and overall less maintenance costs. Pneumatic manifolds enable installation of multiple pneumatic solenoid valves in a centralized location where a single air supply and exhaust port is shared among all valves.
