Company Profile
Product Details
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.
Bullet Points
