Demand Flow Regulators
The Oxford Valves OV-DFR-400 Series is a range of demand flow regulators designed for calibration gases, pump-based instruments, handheld gas detectors, and portable gas calibration systems.
Demand flow regulators supply gas only when demanded by the instrument and automatically shut off when demand stops. This makes them suitable for pumped gas detectors and sampling instruments where gas is drawn only when required.
The OV-DFR-400 Series includes C10, CGA600, high pressure, brass nickel plated, stainless steel, aluminium hard anodised, and 45-degree outlet configurations.
OV-DFR-401 C10 Demand Flow Regulator, Brass Nickel Plated Configuration
The OV-DFR-401 is a C10 demand flow regulator used for calibration gases, pump-based instruments, and handheld gas detectors. It supplies gas as demanded by the instrument and automatically shuts off when demand stops.
