Pressure switch Dungs GGW50A4 246176

Dungs GGW50A4 246176 air pressure switch is an adjustable differential pressure switch designed for automatic burner control systems. Dungs GGW50A4 246176 differential pressure switch is suitable for activating, deactivating, or switching a circuit based on changes in the actual pressure relative to the set reference value. The reference value, or switching point, can be adjusted using a setting wheel equipped with a scale. Dungs GGW50A4 246176 differential pressure switch features an integrated test nipple within its metal housing as a standard component.
