The 'G' Series diaphragm, developed from Introl's successful 'A' Series, features a special rolling diaphragm that allows for long travels without needing expensive parts. It offers various spring options, and ball thrust races reduce stress on the diaphragm and make spring compression easier. The design is modular, making it easy to add extra features without changing the main unit.
