V-15: Use of Residual Pressure Valves

Abstract

Cylinder valves that retain a residual positive pressure in a gas cylinder and some types of devices that prevent backflow of fluid by means of a non-return device, commonly referred to as residual pressure valves (RPV), have been available for many years. Important benefits of RPVs include preventing moisture ingress and contamination, which reduce the potential for internal cylinder corrosion. Additional benefits include productivity improvements in the cylinder fill operation, avoiding internal cylinder contamination that could create hazardous situations, and reducing cylinder maintenance.

This publication is intended for use by the compressed gas industry and provides guidelines for the use of RPVs. This publication does not describe any design qualification tests of RPVs.

It gives guidance on the selection, operation, maintenance, and installation of these valves, so common practices are established across the gas industry and these valves are beneficial to both the end user and gas cylinder filling facilities.
