Manufacturer series reference. Confirm the exact order code, mating parts and stated conditions for the quoted configuration.

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.
