Resideo FV300 Filling Valve Float Controlled

The CONCOA 315 Series is a chrome-plated brass, dual-stage cylinder regulator designed for inert and non-corrosive gases in medical laboratory applications. Its two-stage design ensures stable outlet pressure or flow by compensating for gradual cylinder pressure drops. The regulator provides point-of-use control across five pressure ranges, from 0–15 PSIG (0–2 BAR) to 0–200 PSIG (0–14 BAR). It comes with a standard 2–15 lpm flowgauge calibrated for CO₂ (for lasers and cell growth chambers) or a custom thermal mass flowmeter-calibrated gauge for specific gases. While suitable for medical lab use, it is not intended for therapeutic use in humans.

The Valfonta S3 Straight Pattern Pressure Relief Valve is designed to effectively regulate upstream pressure, maintaining it at a predetermined set point. When the upstream pressure exceeds this set point, the valve opens proportionally, allowing for the controlled release of excess pressure.
