The Pin Index Valve back on the rise - NEW GCE Medical Valves

Published on 1 July 2020 by

Sir Humphrey Davey (also the inventor of the Davey lamp) first began using gases for pain relief in the 19th Century.

In 1844, Gardner Quincy Colton, an American showman, medicine man, lecturer, and former medical student presented a demonstration of nitrous oxide inhalation, and the need to assure the correct gas was being connected was born.

The US Fire Protection Association, together with CGA along with the American Society of Anaesthesiologists designed the Pin Index system in 1952.

The extremely compact valve design uses geometrically arranged pins and hollows surrounding the gas connection eliminates the risk of accidental connection of an incorrect gas.

In recent years, however, customer needs demand both higher purity and greater medicinal integrity levels within each gas cylinder, requiring the inclusion of a Residual Pressure Device (RPD).

But the beneficially compact size of the Pin Index valve makes this an extremely challenging technical hurdle.

GCE is delighted to bring to the Global Market their new PIN index valves with RPD to fulfil all of these needs.
