Frequently asked questions about laboratory gas systems and valves.
Lab gas line check valve installation requires flow direction alignment, pressure matching (cracking ≤0.02MPa), and gas-compatible designs (oxygen-clean, anti-static).
PTFE-lined stainless steel hoses or PU tubes are suitable for lab low-pressure gas lines (≤0.5MPa), avoiding PVC tubes.
Double-ended bulkhead unions ensure sealing, pipe alignment, and easy maintenance for lab gas line wall penetrations.
Lab gas line filters (0.2μm pore size) install downstream of relief valves, with regular element replacement every 3-6 months.
Choose gas pressure relief valves for lab manifolds based on gas type, pressure range (0-20MPa inlet), and CE/ASME certification.
