GCE Druva Absolute Pressure Regulators
An absolute pressure regulator (APR) maintains a constant downstream pressure relative to a perfect vacuum (zero pressure), not atmospheric pressure like standard gauge regulators, making it ideal for precise control in high-purity, vacuum, or sensitive applications such as semiconductor manufacturing, medical devices, and research labs. These regulators adjust gas/liquid flow to achieve a specific setpoint (e.g., in psia, bar(a)), working below atmospheric pressure or at low positive pressures, and often feature advanced materials and digital controls for high accuracy.
