ISO 22434:2006规定了气瓶阀的检查和维护要求，包括带集成压力调节器（VIPR）的阀门（见ISO 22435）。 ISO 22434:2006可以在气瓶，束，滚筒和拖车的定期检查时，以及在任何其他时间，例如，在改变燃气服务（见ISO 11621）。它不适用于在气瓶充填时执行的气缸阀的常规检查

ISO 22434:2006 specifies the requirements for the inspection and maintenance of cylinder valves, including valves with integrated pressure regulators (VIPR) (see ISO 22435). ISO 22434:2006 may be applied to cylinder valves at the time of the periodic inspection of gas cylinders, bundles, drums and trailers, and at any other time, e.g. at change of gas service (see ISO 11621). It does not apply to routine inspection of cylinder valves carried out at the time of cylinder filling.
