Ball Valves Type T With Brazing Connection

Ball valves type T, with brazing fittings, brass nickel-plated, ungreased for oxygen and other industrial gases or compressed air, with pressure up to 40 bar.

Due to the safe handling and easy installation features of ball valves with brazing connection, they are the main choice for use as shut off valves in copper tube systems for oxygen and other compressed industrial gases. The valve type T as descibed below, consists of the valve, 2 connection adapters, 2 female brazing ends plus corresponding nuts. The threaded adapters are mounted into the valve only using the thread and a sealing area with an oxygen-proof o-ring.

The adaptors male thread ends are shaped 60 degrees conically, getting smaller  to the inside. After the integration into the copper tube (brazing!) the conically shaped brazing ends are connected to the corresponding sealing area at the adaptor/valve and tight-sealed through fastening the nuts.

The ball valve is tested acc. to DIN 32509 and can be used with following gases:

Oxygen, Nitrogen,  CO2 (Carbon Dioxide), Argon, Helium and other Inert Gases, Hydrogen, Synthetic Air, Compressed Air, Laughing Gas and other non-corrosive gases
