VICI/Valco EUTA-SF16MWE Selector Valve
| Attribute | Specification |
|---|---|
| Manufacturer | VICI Valco Instruments Co. Inc. |
| Model | EUTA-SF16MWE (16-position flow-through selector with universal actuator, RS-232 interface) |
| Product Type | Multi-position selector valve (flow-through, SF flowpath) |
| Flowpath Configuration | Flow-through (SF) — non-selected streams flow through individual outlets |
| Number of Positions | 16 positions |
| Actuation / Interface | Universal actuator with RS-232 interface |
| Fitting Size | 1⁄8″ fittings (1.0 mm port size) — typical for SF 1⁄8″ series |
| Port Bore | Approximately 1.0 mm (common for SF 1⁄8″ valves) |
| Body Material | Nitronic 60 stainless steel alloy (standard low-pressure selector body) |
| Rotor Material | Valcon E (polyaryletherketone/PTFE composite) |
| Maximum Pressure (gas) | 200 psi (≈ 13.8 bar) for low-pressure selectors (typical rating) |
| Maximum Temperature | 200 °C (rated for low-pressure selector body and rotor) |
| Compatibility | Gas chromatography (< 200 psi, low-pressure analytical applications) |
| Actuator Options | Manual (not recommended), pneumatic, microelectric, universal (with RS-232/485/USB, BCD options) |
| Standoff Options | Optional standoffs (2″, 3″, 4″, 6″) for mounting actuator outside heated zones (GC applications) |
| Valve Series | SF — Flow-through selector series (low pressure) |
| Typical Use Cases | Multi-stream gas routing or sampling in analytical systems (e.g., GC sample selection) |
| Valve Replacement Parts | Rotor and complete valve options available separately (e.g., DSF16MWE, SSASF16MWE) |
