In 1955, Bellofram Corporation introduced the rolling seal diaphragm design for a line of low-friction cylinders and soon adapted the design to a new line of gas pressure regulators. This new rolling seal diaphragm design produced a gas regulator of unsurpassed precision and repeatability. This design innovation is present in the entire line of Marsh Bellofram regulators, relays, I/P’s and E/P’s.
