Product Description

Nitrogen gas regulators are used to control the pressure and incoming gas flow from the nitrogen cylinder or bank of cylinders. The dual gauge allows visual control of both the inlet and outlet pressure.

Application

When pre-charging hydraulic accumulators it is important that initially the accumulator be charged slowly. This is due to the fact that the bladder / diaphragm has to expand and stretch uniformly to take up the volume of the vessel internally. The pressure required to do this properly is less than 1 bar. Pre-charging an accumulator too quickly and/or without the correct lubrication can damage or in some cases cause failure of the bladder / diaphragm. In order to pre-charge an accumulator properly STAUFF recommends the use of a nitrogen gas regulator.
