DIN EN ISO 10297:2024-11

This standard specifies design, type testing and marking requirements for: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for bundles of cylinders; c) cylinder valves or main valves with integrated pressure regulator (VIPR); d) valves for pressure drums and tubes which convey compressed, liquefied or dissolved gases. This includes the following specific VIPR designs where: 1) The pressure regulating system is acting as the primary valve operating mechanism (VIPR type B). This also includes designs where closure of the primary valve operating mechanism is obtained by closing the seat of the pressure regulating mechanism. 2) The primary valve operating mechanism is located at the low-pressure side of the pressure regulating system (VIPR type C).
