Multi-Position GC Selection Valves - Up to 16 Ports
With stepper motor
Description
These GC multi-position selection valves are widely used in laboratory gas chromatography instruments, VOC gas analyzers, petrochemical multi-column switching systems, and laboratory gas-flow control setups for analytical processes.
- Rotor surface‑treated to prevent adhesion and reduce torque

- Pressure resistance: 6.9 bar | 100 psi (gas)
- Up to 16 ports
- Orifice sizes: 0.40 mm, 0.75 mm, 1.0 mm
- Rotor material: Nitronic 60 (other optionally available materials, e.g., Hastelloy alloys)
- Extension rods: 2", 3", 4", 6"
- Optional: Rotor surface passivation
Optional valve configurations:
- With common exhaust port
- With independent exhaust port
