Product Overview
The DA22 Series Dual Stage Medium Flow Automatic Switching Supply Gas Control Panel is designed for dual-sided gas cylinder pressure reduction and continuous gas supply. It supports main and standby gas source operation and automatically switches to the standby side when the pressure of the priority side drops below the set value.
With dual stage pressure regulation, selectable inlet direction, pressure gauge options, multiple inlet and outlet connection choices, and optional signal pressure gauge, pressure sensor, or safety valve configuration, the DA22 Series is suitable for industrial gas control, specialty gas pipeline, laboratory gas supply, analytical instruments, and research gas systems.

Key Features
Automatic Switching for Continuous Gas Supply
For users who need uninterrupted gas delivery, the DA22 automatic switching structure changes from the priority side to the standby side when cylinder pressure drops below the set value, helping reduce shutdown risk in laboratory and process gas lines.
Dual Stage Pressure Regulation
Dual stage pressure reduction helps keep outlet pressure more stable when inlet cylinder pressure changes, supporting analytical instruments, gas panels, test equipment, and medium flow gas supply systems.
Configurable Connections and Options
Selectable inlet direction, pressure gauge range, inlet and outlet connections, pressure sensor option, signal pressure gauge option, and safety valve option help buyers match the panel to project requirements.
