Two types of changeover system are available which are low pressure electronic (digital ) automatic change over & high pressure mechanical automatic change over. We can connect two cylinders of same gases where cut off pressure or cylinder change over pressure can be programmed in digital automatic & cylinder automatically change from line 1 to line 2 as per program, where as in mechanical automatic , the cut off pressure is done by differential pressure regulators and the change over of the cylinder is done as per differential pressure set.
Manifold system is connected with the Gas cylinder through flexible tail pipe called Pigtail. It is made up of Teflon tubing (inside) and exterior SS wire braided with flexible protection. The end connectors are suitably designed to fit on the Gas cylinder, Regulator as well as Manifold systems.
