Automatic Changeover regulators prevent gas outages by switching supply cylinders over to the reserve cylinder automatically when the primary cylinder is near empty. When the primary cylinder is depleted causing the changeover to occur a red indicator will appear signifying the reserve cylinder in now in use and the primary cylinder can be refilled without loss of service. Reduced the damage from the deterioration by metal abrasion, even though use valve often frequencies.
This regulator equipped convert handle which indicates
“serve“ and “reserve”, and diaphragm operation would help adjusting demand pressure. This compact designed for especially space limitation, and light weight helps to easier installation.
