Specifications and configuration
Reference — SMC FC2W520-04-3-X110
| Parameter | Documented value / configuration |
|---|---|
| Ordering code | FC2W520-04-3-X110; 1/2 in. Rc port; 3 m leadConditions: scope: Exact catalogue ordering example |
| Rated flow control range | 2.0–16.0 L/minConditions: medium: Water; catalogue specified operating conditions |
| Process port | Rc 1/2Conditions: scope: Confirm mating thread and line size in RFQ |
| Working pressure | 0.2–0.4 MPa at 0–50 °C fluid temperature; proof pressure 0.6 MPaConditions: scope: Proof pressure is not the normal working range |
| Control accuracy | ±5% F.S. flow-control accuracy; response time ≤10 sConditions: scope: Catalogue condition; not a fast-acting safety shutoff |
| Power and signal | 24 VDC ±10%; 0–5 VDC analogue flow-command input; flow-pulse outputConditions: scope: Check controls integration and wiring diagram |
| Listed medium and temperature | Water; fluid temperature 0–50 °C without freezingConditions: scope: Do not infer glycol or other coolant compatibility from water rating |
| Shutoff limitation | Controller cannot fully close; an external shutoff valve is needed for emergency stopConditions: scope: Functional boundary of FC2W-X110 series |

Overview
SMC FC2W-X110 automatically adjusts water flow within a preset range. The PDF photograph shows the FC2W520 body and controller; the exact wiring/port suffix is defined by its catalogue ordering code.
Construction and interfaces
The illustrated unit combines two inline threaded ports, an electrically powered controller and a local status interface. The pictured series body is complete and suitable as a local reference main image.
Selection
The FC2W520-04-3-X110 example uses Rc 1/2 ports and controls 2–16 L/min of water at 0–50 °C. Published normal pressure is 0.2–0.4 MPa; 0.6 MPa is a separate proof value.
Configuration options
The same family includes a smaller FC2W504 range. Confirm the exact model code, port size, 3 m lead, 24 VDC supply, analogue command and pulse-output interface before specifying controls.
Application limits
The catalogue says the controller does not fully close, so use a separate shutoff valve for emergency stop. Do not assume glycol or other coolant compatibility from this water-only entry.
