A throttling device that reduces stream pressure with no moving parts.
Parameters
| Parameter | Type | Unit | Description |
|---|
| outletP | Quantity | bar, Pa, psi | Outlet pressure (specify one) |
| dP | Quantity | bar, Pa, psi | Pressure drop (specify one) |
Specify either outletP or dP — the other is calculated automatically.
Modes
| Mode | Description |
|---|
| Quick | Isenthalpic flash — assumes H_out = H_in and solves for outlet T at the new pressure |
| Rigorous | IDAES Valve model with full thermodynamic property evaluation |
Ports
| Port | Direction | Description |
|---|
| in | Input | Inlet stream |
| out | Output | Outlet stream (lower pressure) |
