Gas Pressure Switch
Dungs GW Series Gas Pressure Switch
The Dungs GW series are compact gas pressure monitors built for the safety circuit of gas burners and industrial heating plant. Each unit watches the gas pressure at the burner and breaks the circuit when pressure falls outside the set band, so the burner control can shut down safely instead of firing on a starved or over-pressured line. Zhongli Weiye stocks the GW 150 A6, GW 500 A5 and GW 50 A5 variants and helps buyers match the right setpoint, thread and switching differential to their burner train.
Why buyers choose it
- Monitors gas pressure and opens the safety circuit on out-of-band pressure, protecting the burner train.
- Compact aluminum housing suits tight burner-front and panel-mount installations.
- Multiple setpoint ranges across the GW 150 / 500 / 50 line cover light commercial to industrial burners.
- Stocked by Zhongli Weiye with selection help so the matching model, thread and differential ship first time.
