How to add a Generic D03 Interface in a Schematic when valve information is not available

Overview

When designing a manifold schematic, there may be cases where the exact valve models are not yet finalized. However, the designer may already know the mounting interface, such as D03. In such situations, a generic interface symbol can be used in the schematic until the final valve models are selected.


Solution

To represent a D03 interface in the schematic when the valve model is unknown:
  1. Create or use a generic symbol representing the interface.
  2. Assign the Cavity/Footprint/Interface name (e.g., D03) to the symbol.
  3. Include the standard four ports: P, T, A, B
  4. Place this symbol in the manifold schematic to represent the interface location.

Alternative Method

If a dedicated symbol is not available, the interface can also be represented as a simple element containing only four ports (P, T, A, B).


This allows the schematic to be created while leaving flexibility to update the symbol later when the final valve model is known.

Notes

  1. This technique is commonly used when designing sandwich manifolds.
  2. The generic symbol can later be replaced with the actual valve symbol once the specific component model is determined.
