This valve is suitable for gas chromatographs or other instruments to ensure stable output flow rate (referring to mass flow rate) when the input pressure of carrier gas, auxiliary gas, and other gas sources is unstable and the output pressure changes.
Input pressure: ≤ 0.45Mpa
Output flow range: 0-300ml/min 0-500ml/min 0-1000ml/min 0-2000ml/min
Airtightness: 0.4Mpa/cm2
Stability: The flow rate does not change by more than 1.5% ml within 15-30 minutes
Installation size: External size: Φ 38 × 103 Installation hole: Φ 12.5 Inlet and outlet external joint: M8 × 1 (one inlet and two outlets)
