Diese Norm gilt für Maße und Bezeichnung von Anschluss-Kugelhähnen in Eckform mit kegelförmigem Anschluss für Installationen, die mit Gasen nach DVGW-Arbeitsblatt G 260 und mit zulässigen Betriebsüberdrücken von 5 bar betrieben werden.

Diese Norm gilt für Formen, Maße und Bezeichnung von Tüllen mit Dichtring für Installationen, die mit Gasen nach DVGW-Arbeitsblatt G 260 und mit zulässigen Betriebsüberdrücken bis 5 bar betrieben werden.

This Standard applies to newly produced automatic valves (see Clause 3, Definitions) constructed entirely of new, unused parts and materials. These valves may be individual automatic valves or valves utilized as parts of automatic gas ignition systems. This...

Diese Norm gilt für Maße und Bezeichnung von Anschluss-Kugelhähnen in Durchgangsform mit kegelförmigem Anschluss für Installationen, die mit Gasen nach DVGW-Arbeitsblatt G 260 und mit zulässigen Betriebsüberdrücken von 5 bar betrieben werden.

This document lists the different valve stem to gas cylinder connection threads currently and historically existing worldwide and provides official coded designations for them. These coded designations will then be available for identification and marking purposes. It also gives...

This Standard applies to manual lever operated, gas shut-off valves sizes NPS 1/4 to 8 of metallic construction with weld and flanged and threaded ends other than pressure lubricated designs for use with natural gas, manufactured gas, and liquefied petroleum gases...

Essential mechanical properties of materials for gas cylinder valves for breathing purposes (other than medical). Thread dimensions for four sizes of valve stems plus details of manufacturing gauges. Dimensional drawings for valve outlet connections.

Specifies requirements and methods of test for type approval of hand wheel or key operated valves for use on gas cylinders up to 150 l water capacity. It is not applicable to valves for use on breathing equipment, fire extingushers, cryogenic equipment or LPG equipment.

This standard applies to cylinder valves according to DIN EN ISO 10297 for compressed, liquefied and dissolved gases. This standard specifies the requirements for inlet and outlet connections of cylinder valves rated for cylinder test pressures up to and including 300 bar, if...
