High-Accuracy One Inch Lighter Gas Regulation Valve for Analytical
Instrumentation with Micrometer Calibration and Zero-Emission Seals
Product Description:
Precision-engineered for laboratory environments, this one-inch
lighter gas valve enables micron-level flow control in GC/MS
systems, calibration rigs, and research burners. The 316L stainless
steel body features bellows-sealed stems that eliminate external
leakage (tested to <1×10⁻⁹ cc/sec helium), while electropolished
internals prevent gas adsorption. With a 200-position micrometer
knob, technicians achieve ±0.5% flow accuracy across 0.01-50 SCFH
ranges – critical for reproducible analytical results. VCR
face-seal fittings maintain ultra-high purity standards (ISO Class
3 cleanroom compatible), and all wetted surfaces meet USP Class VI
requirements. The integrated pressure gauge port allows real-time
monitoring without flow disruption. Designed for oxygen service and
cryogenic applications (-196°C to 150°C), this gas metering valve
ships with NIST-traceable calibration certificates. Applications
include pharmaceutical lab reactors, semiconductor fabrication gas
panels, and emissions testing equipment where precise fuel
modulation is non-negotiable.
