Premier - Model 4902 Series -Demand Flow Regulators
The Premier 4902 Series Demand Flow Regulators are engineered to supply gas on demand for analytical instrumentation while maintaining an efficient and user-friendly operation. These regulators are designed with a unique single-stage vacuum-actuated system that is patented for its sensitivity and efficiency, allowing for rapid testing as they maintain flow at pressures below one inch of water column. Their robust construction offers options in 6061-T6 aluminum, nickel-plated brass, and stainless steel, along with customizable porting options, wetted materials, o-ring seals, elastomers, and gauges to meet various application needs. These regulators facilitate seamless calibration by obviating the need for sample bags or flow meters, thus conserving expensive calibration gases. Ideally used in calibration gas environments, Premier 4902 Series caters to a multitude of analyzers interfaced on a single docking station, aiming to streamline operations and reduce operational downtime.Premier’s patented, efficient, and easy to use 4902 Series demand flow regulators (also referred to as “sample regulators” and “vacuum actuated regulators”) supply gas as demanded by an analyzer and automatically shut off. The highly sensitive, patented, single stage design allows for reduced testing time, permitting the flow of gas at less than one inch water column. Furthermore, the high flow capacity of the Premier 4902 Series demand flow regulator enables multiple analyzers to be tested on a single docking station.
Premier 4902 Series regulators offer great flexibility, available in 6061-T6 aluminum, nickel plated brass, and stainless steel, with a variety of: porting options, wetted materials, o-ring seals, elastomers, gauges, and other additional options.
Premier demand flow regulators make calibration quick and easy by eliminating the need for sample bags, flow meters, or special operator training; they also save on expensive calibration gases by only transferring as much gas as demanded by the instrument.
