Gas cylinders. Residual pressure valves. Specification and type testing of cylinder valves incorporating residual pressure devices Ingestion-build-183511 The results of these tests1 Scope This document specifies design, type testing and marking requirements for cylinder valves incorporating residual pressure devices, hereinafter referred to as residual pressure valves (RPVs). This document applies to the following types of RPVs: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for cylinder bundles; c) cylinder valves or main valves with integrated
