The Chirana PL-40 is a two stage regulator and its design

They were used exclusively in the CSSR (Czechoslovak Socialist Republic) and were not intended for export.
Only after the turn of 1989, a few copies arrived in the hands
of the collectors all over the world.
The company Chirana, located in Stará Turá, city of the
Czech Republic, was founded in 1935. The activity was the production of parts for water meters and gas meters. The current production line is for the manufacture of medical and ondontological products.
