Abstract
The present invention relates to a fluid cylinder pressure check valve device, for use during the recharging of cylinders with fluid(s). In use, the invention is attached to a valve assembly of the cylinder so that when the valve assembly is opened, residual pressure within the cylinder may be determined to enable more efficient recharging. The invention also allows cylinders containing gas mixtures to be recharged to attain enhanced composition uniformity.
